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.

i think you can ignore the words, and factor \[x^2+24x+162\]

or see which product multiplies out to \(x^2+27x+162\) pretty clearly it is not A,, B or even D since the product of the last two numbers has to be \(162\)

it is not factorable

sure it is

\[18\times 9=162\] and \[18+9=27\]
