Question 1028071: Level 3: 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? Check all that apply.

750 – y(y – 5) = 0

y(y + 5) = 750

y(y – 5) + 750 = 0

(y + 25)(y – 30) = 0

y2 – 5y = 750
