You can put this solution on YOUR website! I need help solving this question The perimeter of the quandrilateral is 43 centimeters. find the length of each side x+7, x2-3x, 3x-2, x+3
---------------------
x+7 + x^2-3x + 3x-2 + x+3 = 43
-------
x^2 +2x +8 = 43
x^2 + 2x - 35 = 0
----
Factor:
(x+7)(x-5) = 0
----
Usable answer: x = 5
----
Sides:
x+7 = 12
x^2-3x = 10
3x-2 = 13
x+3 = 8
