Simplify. Write in Standard Form. r²(r+1)-r(2r²-1)
PLEASE EXPLAIN HOW YOU GOT IT!!!!
Answer:
−r^3+r^2+r
Step-by-step explanation:
Let's simplify step-by-step.
r^2(r+1)−r(2r^2−1)
Distribute:
=(r^2)(r)+(r^2)(1)+−2r^3+r
=r^3+r^2+−2r^3+r
Combine Like Terms:
=r^3+r^2+−2r^3+r
=(r^3+−2r^3)+(r^2)+(r)
=−r^3+r^2+r

B. Substitution Method
Step-by-step explanation:
You already have what "y" equals, so you can substitute that in for the other equation on top.
Decide whether there is enough information to prove that a∥b. If so, state the theorem you would use.
Answer: C) Yes, Alternate Exterior Angles Converse
The two red angles are on the outside of the lines a and b, so they are considered exterior. They alternate on either side of the transversal line. So we consider those red angles to be alternate exterior angles. We'll use the alternate exterior angles converse to prove the lines parallel. That converse states: "If alternate exterior angles are congruent, then the lines are parallel".

Solve. Express your answer as a mixed number. 5 feet= ______ yards Solve. I need an explanation on how to put it as a mixed number and how to solve it.
Answer: 5 feet= __5/3 0r 1 2/3____ yards
Step-by-step explanation:
Step 11 yard = 3 feet
3 feet = 1 yard
5 feet = 5feet x 1 yard/ 3feet
= 5/3yards
Step 2 To convert 5/3 yards to a mixed fraction,
1. We first Divide the numerator, 5 by the denominator, 3 giving us a whole number and a remainder
5/3 = 1 remainder 2
2.then we write the whole number and put the remainder 2 above the denominator 3 giving us
5/3 = 1 2/3
such that when you multiply the mixed fraction 3 x 1 and add 2 it gives back the improper fraction of 5/3

complete the equation 4/5= ____×
1/5
Answer:
HI! I think the answer is 4.
Answer:
4/5 = 4 x 1/5
Step-by-step explanation:
Since we can write 4 as 4/1, that means 4 is the answer. This is because you multiply the top numbers and the bottom numbers, 4x1 is 4, and 1x5 is 5, so that means the answer is 4 since that problem got us 4/5.

Answer:
82 units
Step-by-step explanation:
There are multiple ways to go about solving this problem (solving by calculating the areas of the individual, smaller shapes), but I recommend solving it by first calculating the area of the entire figure (96 units - 12 * 8 - length * width ((formula for the area of a rectangle)) and then subtracting the area of the missing part from this value.Assume the opposite sides are equal in value (see picture for work) and subtract the given values (4 and 5) from 8 and 12 to get the measurements to find the triangle (the missing part).You get 7 and 4 and now you use the formula for the area of a triangle to get the area. (7*4)/2, which gives you 14 units.Subtract 14 (area of missing value) from 96 (area of total value) to get your final answer, 82 units!y = (x – 4)² - 4

Write an equation in point-slope form of the line that passes through the given point and has the given slope (4, -5); m = 6
Answer:
m=6
X1=4
Y1= -5
Y-Y1=m(X-X1)
Y-(-5)=6(X-4)
Y+5=6X-24
Y=6X-24-5
Y=6X-29

Robert is pouring wax into cylindrical candle containers. Approximately 226.19 cubic inches of wax fill one candle jar. Which image represents that volume?
A cylinder with height 8 inches and radius 3 inches.
A cylinder with height 5 inches and radius 4 inches.
A cylinder with height 10 inches and radius 2 inches.
A cylinder with height 5 inches and radius 5 inches.
Answer:
The first choice.
Step-by-step explanation:
The volume must be about 226.19 in^3.
Volume of a cylinder = area of base * height4
= πr^2h = 226.19
r^2 = 226.19 / πh.
Consider the first of the choices:-
When h = 8 , r^2 = 226.19 /8π = 8.9998
So r = 3.00 to nearest hundredth.
So this is the required image.

Does bin width matter when it comes to histograms? Why or why not?
Answer:
Avoid histograms with small bin widths that group data into lots of bins. A histogram constructed with small bin widths will show the distribution as a “pancake.” so no it does not help us see the pattern in the data.
