A piece of cloth is folded into a square with a side length measuring x inches. When it is unfolded, it has an area of x2 + 27x + 162 square inches.

Which could be the dimensions of the rectangular piece of cloth when it is unfolded? Remember, the area of a rectangle can be determined using the formula A = lw.

length = (x + 9) inches and width = (x + 3) inches

length = (x - 3) inches and width = (x - 9) inches

length = (x + 18) inches and width = (x + 9) inches

length = (x - 9) inches and width = (x - 18) inches

Hello,

(x+9) (x+3=x²+21+27 No

(x-3) (x-9) = x²-12x+27 No

(x+18) (x+9) = x²+27x+162 Yes

(x-9) (x-18) = x²-27x+162 No
