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.

1- y(y + 5) = 750
2- y^2 – 5y = 750
3- 750 – y(y – 5) = 0
4- y(y – 5) + 750 = 0
5- (y + 25)(y – 30) = 0
