The perimeter of the quadrilateral is 108 inches. Find the lengths of the sides. The dimensions are x+2 2x+1 x^2-3x and x-5

You can put this solution on YOUR website!
The perimeter of the quadrilateral is 108 inches. Find the lengths of the sides. The dimensions are x+2 2x+1 x^2-3x and x-5
----------------
(x+2) + (2x+1) + (x^2-3x) + (x-5) = 108
x^2 + x -4 = 108
x^2+x-112=0
------
You say you have not had "square root".
This equation requires solution by the
Quadratic Formula which involves square
roots.
Check to see if you have posted the
dimensions properly. Look especially
at the x^2-3x dimension. It is
probably wrong.
