    Yeah i mean the wording is crap. No wonder people get confused when taking math tests.

    The length of a rectangle is 8 less than 5 time it's width. a = l * w
    (5w-8) * w

    The width is increased by three while the length is unchanged.
    (5w - 8) * (w + 3)

    So we should end up with. (5w-8)(w+3) - (5w-8)w
    6w + 15 w -8w -24 -(6w - 8w)
    6w + 15w -8w -24 -6w + 8w
    15w - 24

    I think that's it. Thanks for the help.
