Answer:w =A/1
Step-by-step explanation:
It would be A. A squares width and length are the same so both the width and length can be represented with x. The problem asks to add 5 to the length and 3 to the width creating the expression (x+5)(x+3). That can then be multiplied out to get x^2+8x+15
-9h - 6 + 12h + 40 = 22
3h + 34 = 22
3h = -12
h = -12/3
h = -4
