Answer:
x = - 7
Step-by-step explanation:
Given
4(1 - x) + 2x = - 3(x + 1) ← distribute parenthesis on both sides
4 - 4x + 2x = - 3x - 3, that is
4 - 2x = - 3x - 3 ( add 3x to both sides )
4 + x = - 3 ( subtract 4 from both sides )
x = - 7

Step-by-step explanation:
From the text you can derive the following equations:
(1) A = bh/2 = 8
(2) and h = b+6
Fill in h in (1):
b(b+6)/2 = 8 => b^2 + 6b = 16 with the quadratic formula or simply trying some values for b you can find b=2, so h=8.
