Step-by-step explanation:
x + 2(-x+ 4) = 8
x - 2x - 8 = 8
-x - 8 = 8
-x = 16
x = -16
y = 16 + 4 = 20
(-16, 20)
Answer: x = 52 m
Step-by-step explanation:
The formula we will use, which solves for the area of a trapezoid, is where a is a base, b is a base, and h is the height.
We will input the known values, then solve for <em>x</em>.
