Answer:
x = -7
Step-by-step explanation:
-5( x + 3 ) = 20
Distributive property ( multiply whatever is in the parenthesis by -5)
-5 * x + -5 * 3 = 20
-5x - 15 = 20
Add 15 on both sides
-5x - 15 + 15 = 20 + 15
-5x = 35
Divide by -5 on both sides to isolate the variable
-5x/-5 = 35/-5
x = -7
Check...
Substitute the "x" with -7 since we already got that as our solution
-5( x + 3 ) = 20
-5( -7 + 3 ) = 20
Distributive property
-5 * -7 + -5 * 3 = 20
35 - 15 = 20
20 = 20 CORRECT
Hope this helped!

So we want to find the surface area of this pyramid. Finding the surface area of a 3D shape is essentially finding the area of all its sides and adding them together.
What we're going to have to do here is find the area of the base of the pyramid, which is basically a square, and find the area of all four sides of the pyramid, which are triangles.
Formula for area of a square: length × width
Formula for area of a triangle: (base × height) ÷ 2
First we will find the area of the base:
l × w = A
(Write out formula)
8 × 8 =
(Input values)
A = 64 m^2 (square meters or meters squared)
(We have our answer, dont forgot to write your units.)
So we've figured out the area of the base. Now onto the triangles:
(b×h) ÷ 2 = A
(Write out formula)
(8 × 6) ÷ 2 =
(Input values)
48 ÷ 2 =
(Use PEMDAS to solve this correctly. We did whatever was in the parenthesis first, which was multiplication.)
A = 24m^2 (square meters or meters squared)
(We have our answer.)
Now we've found the area of the base of the pyramid and one of the sides of the pyramid, but we're almost done! There's four sides to the pyramid, they're all the same. So since we found the area for one, we can multiply that by 4 to find the area of all sides added together:
24 × 4
(area of a side × total sides)
= 96m^2
All that's left is adding the 96 to the area of the base to get our total surface area of the pyramid:
96 + 64 = 160
The surface area of the pyramid is 160m^2(square meters or meters squared)
(Hope this helps :) )

Answer these questions about killer whales:
What do killer whales look like? Be very specific, colors, size, length, spots, stripes, camouflage...etc.
What are some facts about killer whales? List at least 5.
I will give brainliest, thanks, friend request, and 5 stars to the best answer.
Answer:
Adult male killer whales are larger overall than their female counterpart including features such as pectoral flippers, dorsal fins, tail flukes, and girth. The largest recorded male killer whale was 9.8 m (32 ft.) in length and weighed 10,000 kg (22,000 lbs.) The largest recorded female was 8.5 m (28 ft.) and weighed 7,500 kg (16,500 lbs.). Data from Icelandic killer whales (North Atlantic type 1) indicate that an average-size male is about 5.8 to 6.7 m (19 to 22 ft.) long, while females averaged 4.9 to 5.8 m (16 to 19 ft.) long. Killer whale sizes vary significantly between different ecotypes.
Male Antarctic type A killer whales can reach lengths of 9.2 m (30 ft.) making them the largest known killer whales. The smallest killer whale ecotype is the Antarctic type C killer whales in which adult females average 5.2 m (17 ft.) and adult males average 5.6 m (18 ft.) in length and can reach a maximum of 6.1 m (20 ft.). At SeaWorld, average size for adult males is 6.6 m (21.7 ft.) Two of the largest adult male killer whales at SeaWorld weigh 4,340 kg (9,570 lbs.) and 5,380 kg (11,860 lbs.).
At SeaWorld, average size for females is 5.5 m (18 ft.) and 2,442 kg. (5,384 lbs.) SeaWorld's adult female whales range in weight from 2,313 kg (5,100 lbs.) to 3,719 kg (8,200 lbs.). The general body shape of a killer whale is roughly cylindrical but tapering at both ends. This characteristic fusiform shape is quite energy efficient for swimming. Killer whales are black and white, with a gray patch called a "saddle" or a "cape" on the back, just behind the dorsal fin. A killer whale's forelimbs are adapted for swimming. A killer whales uses its rounded, paddlelike pectoral flippers to steer and, with the help of the flukes, to stop. A killer whale's pectoral flipper contains 5 digits much like the fingers on a human hand. Each lobe of the two-lobed tail is called a fluke. Flukes are flat pads of tough, dense, fibrous connective tissue, completely without bone or cartilage. Like the flukes, the dorsal fin is made of dense, fibrous connective tissue, without bones or cartilage. A killer whale has an indistinct rostrum (snout-like projection).
A single blowhole on top of the head is covered by a muscular flap. A killer whale breathes through its blowhole. The blowhole is relaxed in a closed position, and the flap provides a water-tight seal. To open its blowhole, a killer whale contracts the muscular flap.
A killer whale's eyes are on each side of its head, just behind and above the corner of its mouth, and in front of its white eyespot.
A killer whale's large teeth are conical and interlocking. Toothed whales have only one set of teeth; they are not replaced once lost. The number of teeth varies among individuals. There are usually 10 to 14 teeth on each side of each jaw (40 to 56 teeth total). A killer whale's blubber layer lies beneath the dermis and measures from 7.6 to 10 cm (3 to 4 in.) thick. Blubber is a layer of fat reinforced by collagen and elastic fibers. In general, blubber has a number of important functions: A killer whale's dermis (skin) is smooth. The outer layer continually and rapidly renews itself, and the old skin sloughs off. The increased skin cell turnover increases swimming efficiency by creating a smooth body surface which reduces drag.
Facts:
1) The name killer whale derives from their original name ‘whale killers’ given to them by sailors who saw them hunting whales. Over time, the name eventually switched around. The name ‘orca‘ comes from their Latin species name Orcinus orca, where orcinus translates to mean ‘Kingdom of the dead’.
2. Despite their name, killer whales are actually a dolphin – the largest species of oceanic dolphin!
3.Whilst they can and do eat prey such as finfish and marine mammals, New Zealand orca have become specialised at hunting sharks and rays. They can often be seen up around rocky reefs and in the shallows of beaches while they are hunting.
4.The average life span of an orca is not too dissimilar to a human, at 50-80 years for females and slightly less for males at 29-60 years.
5.Orca can be seen in every ocean on the earth. They are one of the most successful marine mammals in terms of range.

James borrows $35 from his father for gas, and then borrows $29 more for video games. What integer represents the amount of money that James owes his father?
Answer:
64
Step-by-step explanation:
You just have to add 35 and 29 and the answer is an integer cause it's a whole number.
Answer:
64
Step-by-step explanation:
You are adding more to the first integer 35, so you have to add the next integer 29 to it.
So, the equation would be 35 + 29
First, add 9 and 5 which is 14. Carry the 1 to the next part.
3+2=5
5+1=6
The end result is 64.

Over the summer Hans ran 89 laps for the track and swam 147 laps of the pool. Hans completed twice as many as his friend lee. How many laps did lee run and swim?
Answer:
118
Step-by-step explanation:
Add Hans laps together then divide by two
Answer:
The answer is 118 laps.
Step-by-step explanation:
First you would have to add 89 + 147 to find how many laps Hans ran over the summer.
Then you have to divide the answer from 89 + 147 by 2 which is 236 divided by two because Hans' laps were twice as much as lee's do when you do 236 divided by 2 you get 118. So, Lee ran, and swan 118 laps.

Answer:
60m
Step-by-step explanation:
4×6=24 so you have that first chunk of the left side.
since 12-4= 8 you can tell that the bottom of the "triangle" is 8m
3x8÷2=12 so now youhave one part left.
since we have already inferred that the base of the triangle was 8m we know that the length of the rectangle was 8m. 8×3=24
now you add the three values. 24+12+24=60

This is graphing and if you only want points ill report
Answer:
is the answer t = $2.00 ?????
Answer: The variables are the Cost of the item, and the Total cost.
The other cost, the shipping is given here: $2. So that is not really a variable.
You can use almost any letters you'd like. I'm using C for the item's cost, and T for the total cost in this equation:
C + 2 = T
This question seems to imply that only one item is in the order
Step-by-step explanation:
There may be other ways to do this, if multiple items are ordered.
The variables are the Cost of the item-- and how Many items are purchased.
The Total is also a variable that depends on how many and the cost of the items.
The other cost, the shipping might be a variable in other questions (not here) here: S could be a variable if it is a percentage ot the cost.
You can use almost any letters you'd like. I'm using C for the item's cost, M for the number of items, S for variable shipping, and T for the total cost in this equation:
M×C + S = T
