    Answer: 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
