...and is the order you multiply to solve:
(x + 5)(2x - 6) =
(x)(2x) = 2x²
(x)(-6) = -6x
(5)(2x) = 10x
(5)(-6) = -30
Combine like terms. Simplify:
2x² -6x + 10x - 30 = 2x² (-6x + 10x) - 30 = 2x² + 4x - 30
2x² + 4x - 30 is your answer.

Steve set the equation equal to 50 which is the entire length of JL. instead he should've set the equation equal to 25, since it's half of 50 and would represent the midpoint. he should've said 2x + 5 = 25
First question: B - 500/9
Second question: A - 6
What you need to do is do the inverse operation on both sides. So right now, 8 is being multiplied by h, so the inverse operation is division. You divide by 8 on both sides to get what h equals. So your equation looks like:
8h/8=112/8
8h/8 cancels out, so you are left only with h. 112 divided by 8 is 14, so your left with h=14 and that is your answer.
