The perimeter of the shape below is 11x2+7x + 1
Find the length of the missing side.



−4x2−2x−7

4x2−8

−4x2−2x2+12

4x2+5

Answer 1

Answer:Ez

Step-by-step explanation:

−4x2−2x−7=6

4x2−8=0

−4x2−2x2+12=0

4x2+5=13

Missing side gotta be 7x^2+3x+2

Answer 2

4x²+5

Explanation:

Since Perimeter is equal to sum of all sides.

Let the missing side be a.

Perimeter = 2x-3 + 7x²+3x +2 +2x - 3 + a

Since we are given a perimeter, so

11x² + 7x + 1 = 2x-3 + 7x²+3x +2 +2x - 3 + a

Combine like terms.

11x²+7x+1 = 7x²+7x -4 + a

Isolate a

11x²+7x+1 -7x²-7x +4 = a

a = 4x²+5

Therefore, the missing side is 4x²+5
