Answer: 750 - y(y-5)=0

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
