-7 = 2x + 8
Solve for x. First subtract 8 to both sides.
-7 - (8) = 2x + 8 - (8)
-15 = 2x
Divide by 2.
-15/(2) = -2x/(2)
x = -15/2 = -7.5
The answer is 28 units squared
Since the base is 4x4, and the height is 2, you'll use the 2 as the height of the netting and the 4 as the length. so, it will be 2x4 which is 8ft^2
It would be $75.
Becuase, $15 divided by 2 years equals $7.50 a year.
Therefore, $7.50 X The 10 years would be $75.
Hope that helped.
