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

side 1: x^2-2x
side 2: 3x-4
side 3: x+2
side 4: x+9

The perimeter is the sum of all the sides so we can add all the sides and set it equal to 35:


Now we have a quadratic so we can use the quadratic formula to find x=. Now you can plug that into each x to find each side:-)

I’m pretty sure the answer is a
