Answer:
area = 12x² + 88x + 96
perimeter = 16x + 40
Step-by-step explanation:
Rectangle.
Length = 2x + 12
Width = 6x + 8
area = length × width
area = (2x + 12)(6x + 8)
area = 12x² + 16x + 72x + 96
area = 12x² + 88x + 96
perimeter = 2(length + width)
perimeter = 2(2x + 12 + 6x + 8)
perimeter = 2(8x + 20)
perimeter = 16x + 40
Function is represented by the equation y=3x-2. and tunction Fis shown on the graph below. Which statement about both functions is true?
HURRY PLEASE
Answer:
I believe it would be both functions have a y-intercept of -2.
Step-by-step explanation:
Hope this answer is correct and helps you. :)
The true statement about the function is that both functions have a y-intercept of -2.
How to explain the functionIf both functions have a y-intercept of -2, it means that they pass through the point (0, -2). The y-intercept is the value of y when x is equal to 0.
Here are many functions that have a y-intercept of -2. Here are a few examples:
Linear function: y = 2x - 2
Quadratic function: y = x² - 2
Logarithmic function: y = log(x) - 2
In general, any function of the form y = mx + b, where m and b are constants, will have a y-intercept of b. So, as long as b = -2, the function will have a y-intercept of -2.

Another Quick question, True Or False: An acute and an obtuse angle are always supplementary
Explain please
Answer:
false
Step-by-step explanation:
Supplementary means that two angles added together must equal 180. An acute angle is one less than 90 degrees, and an obtuse one is greater than 90. They will not always add up to 180.
For example, 24 is an acute angle. 134 is an obtuse angle. But they do not add up to 180 degrees, thus not supplementary.
Answer: True

Find the median of 85, 42, 64, 71, 39, 56, 26
Answer:
56
Step-by-step explanation:
1. first order the numbers from least to greatest (26, 39, 42, 56, 64, 71, 85)
2. Then count how many numbers you have and divide it by 2. We have 7 numbers, so we’ll divide by 2 and round up because 7 is an odd number. (7 divided by 2 =3.5, rounded up is 4.)
3. Now we know the position of the number is this 4th spot, so the median is 56.
The median of the given set of numbers is 56.
What is the median of data?
The median is defined as the value range. To get it, arrange the numbers in ascending order from smallest to largest, then hide one number on either end until you reach the center.
The given set of data as:
{85, 42, 64, 71, 39, 56, 26}
Let's arrange the given numbers in ascending order: 26, 39, 42, 56, 64, 71, 85.
Since we have 7 numbers, which is an odd count, the median is the middle number.
In this case, the middle number is the fourth number, which is 56.
Therefore, the median of the given set of numbers is 56.

Answer:
first question: c. x = 1
6. B. y = -2x - 8
Step-by-step explanation:
first question:
perpendicular means that when it intersects, it makes a right angle.
the equation y = 5 would be parallel to any of the answers with y = ___ because all of those would result in horizontal lines
either of the x = ___ would be perpendicular to y = 5
since it has to pass through the point (1,3) that means that the equation must be x = 1
the equation x = 1 passes through any point beginning with (1 , _)
6.
parallel means that the equations have the same slope. therefore, we can eliminate both A and C
using the given point (-2 , -4),we can plug into the y = mx + b format to solve
m = -2 x = -2 y = -4
-4 = (-2)(-2) + b --> -4 = 4 + b --> b = -8
finally, our equation comes out to be y = -2x - 8

Which situation involves a conditional probability? O A. The probability that you roll a 6 on a number cube B. The probability that you make two free throws in basketball C. The probability that you make a second free throw given that you made the first free throw O D. The probability that you are given a book for your birthday
Answer:
c
Step-by-step explanation:
its conditional because you might not make the first free throw.
The situation that involves a conditional probability is the probability that you make a second free throw given that you made the first free throw.
Thus, option (C) is correct.
Conditional probability refers to the probability of an event occurring given that another event has already occurred.
In this case, the probability of making a second free throw is dependent on the condition that you made the first free throw.
Therefore, the probability that you make a second free throw given that you made the first free throw.

The hight of a regular quadrilateral prism is h=13cm and its lateral area is 624 cm squared. Find the surface area of the prism
Answer:
912 cm^2
Step-by-step explanation:
The total surface area of a 3-dimensional object is the sum of the areas of the faces or surfaces of a 3-dimensional object
Lateral area of a prism = 4 x height x sides
624 = 4 x 13 x s
s = 12
Surface area = 2 x 12^2 + 624
(2 x 144) + 624 = 912 cm^2
At a football match, 25% of the spectators wore red T-shirts and 3750 spectators did not wear red T-shirts. How many spectators were there
Answer:
5000
Step-by-step explanation:
Given data
25% wore red-T shirt
75% did not wear red T-shirt= 3750
Let the total spectator be represented by 100%
Let the total be x
75/100*x= 3750
0.75x= 3750
x= 3750/0.75
x= 5000
Hence thte total number of spectators is 5000
x + 2y = 10
x + 3y = 15
