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? Select three options.

750 - y(y-5)=0

Step-by-step explanation:

Problem: Area of the room = 750 square feet

 Width = Length - 5 feet

We have a rectangular room. To calculate it's area we do:

Area = Width x Length

We know that width depends on Length in this exercise. Replacing our data above:

750 square feet = (Length - 5 feet) x Length

Let's rearrange our equation. If we named Length = y :

Now we do one more final step to match one of the options:

If you look carefully, there are two more correct answers similar to the equation above: y^{2}-5y=750
