    Find length of sides of quadrilateral; write equation with variable x

    Hello all,

    I have a seemingly simple question. I have a quadrilateral with sides (starting with the left side, moving clockwise): (7-x), (x+2), (2x-1), (x-3).

    a) write an equation for the perimeter and simplify: that's easy, and done. This ends up as 3x+5

    b) Find the length of all sides. Using the result from above, 3x+5 = -5/3, and would give one of the sides a -negative answer. I assume one cannot have a negative length?

    Your thoughts and help will be great;y appreciated.

    Kindly,

    David Dudek

    In coordinate geometry each point must have an x,y value
