Question

The perimeter of a quadrilateral is 35 centimeters. Find the length of each side.

Answer 1

The perimeter is the sum of all the sides so we can add all the sides and set it equal to 35:
$x^2-2x+3x-4+x+2+x+9=x^2+3x+7$

Now we have a quadratic so we can use the quadratic formula to find x=$\frac{-3+i \sqrt{19} }{2}$. Now you can plug that into each x to find each side:-)
