You have to make sure that whatever you do to one side, you also do to the other.
2x + 37 = 8x + 7
2x + 37 - 2x = 8x + 7 - 2x
37 = 6x + 7
37 - 7 = 6x + 7 - 7
30 = 6x
30 / 6 = 6x / 6
5 = x
x = 5
Hope this helps! :)
Your answer is going to y = lx + 4l + 2
Answer:
B
Step-by-step explanation:
Given
V = 
Substitute the given values for B and h into the formula
V =
=
= 140 in³
divide 63 by9
63 / 9 = 7
each piece is 7 meters long
if we subtract from 65° the subangle of 37°, what we're left with is an angle off 65° - 37°, Check the picture below.
