Answer:
Step-by-step explanation:
Formula
A = L * W
Givens
W = W
L = W + 2
Solution
Area = L*W
Area = (W+2)*W = 80 Remove the brackets.
Area = W^2 + 2W = 80 Subtract 80 from both sides.
Area = w^2+2W-80=80-80 Combine
Area = w^2 +2W-80 = 0 Factor.
Area = (w+10)(w - 8) = 0
W + 10 = 0 won't work
W = - 10 which isn't possible
W- 8 = 0
W = 8
L = 8 + 2 = 10
The answer looks like A
Answer:
x = −6
Step-by-step explanation:
I like to start off by simplifying the equation! Then, I use inverse operations to narrow it down until I reach the answer!
5x + 12= −18
5x + 12 <u>− 12</u>= −18 <u>− 12
</u>
5x = −30
5x<u>/5</u> = -30<u>/5</u>
<u>x = -6</u>
