PLEASE ANSWER FAST ITS A TIMED TEST What is a simplified expression for the perimeter of the polygon?

A polygon has 6 uneven sides with side lengths: 6 x + 2 y, y squared, 6 x + 2 y, y squared, 4 x squared, and x squared + y.

5x to the second power +y to the second power +3x +4y

86

Step-by-step explanation:

idk

2425

step-by-step explanation:

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
