The area of a rectangular room is 750 square feet. The width of the room is 5 feet less than the length of the room. Which equations can be used to solve for y , the length of the room? Choose three correct answers.

Let the length be y feet, so the width is y − 5 feet. Using area = length × width gives y(y − 5) = 750, which is choice C. Rearranging gives 750 − y(y − 5) = 0, as in choice A, or y² − 5y − 750 = 0; factoring gives (y + 25)(y − 30) = 0, as in choice B.
