The two angles on top are supplementary angles meaning they should add up to 180
72+3x=180
3x=180-72
3x=108
x=36
Mark me brainliest!
Answer:
yeah it is
y is directly proportional to x
proportionality constant is 9
So, this is the answers you get from plugging in x = (7 through 10)
x = 7 ... 24
x = 8 ... 36
x = 9 ... 50
x = 10 ... 66
Then you get the rate of changes...
66 - 50 = 16
50 - 36 = 14
36 - 24 = 12
So the average of 16, 14 and 12 (those values added together and then that total divided by the number of values, which is 3) is 14
The average rate of change is 14
Answer:
<h2><u>
158 in²</u></h2>
Step-by-step explanation:
First we can write the equation to find the surface area of a rectangular prism
Now rewrite filling in variables

Solve. Keep in mind the order of operations
After solving, you should get 158.
Since these measurements were done in inches, we need to add inches/in to the end.
Also, since it is area, we need to add ²
<u>158 in²</u>
