A. The perimeter of the square is 4(x + 3), and the perimeter of the triangle is 3(3x-1)
Because the perimeters are the same. 4(x + 3) = 3(3x - 1). Try substituting 37
equation. Do you get a true statement? Explain.

1 1/7 hope i

step-by-step explanation:

8/7 = (1 * 7 + 1) / 7 = 1 + 1/7 = 1 1/7

is there a question here?

step-by-step explanation:

d. you cannot tell because there are no values shown.

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
