Question
Represent each given condition using a single variable, $x$.The area of the rectangle is 84 square inches. Find its length and width.
Step 1
The area of a rectangle is given by the formula $A = lw$, where $l$ is the length and $w$ is the width. We are also given that the length is $x+3$ and the width is $x-2$. So we can write the equation as $(x+3)(x-2) = 84$. Show more…
