ANSWER RIGHT NOW FOR BRAINLIST!!!

Answer 1

The perimeter is 4/3x(3), or 12/3x.
The area is (2x+2)^2
Therefore, we must solve the equation
4x^2+4x+1= 0
This eventually factors to x = -0.5.

Answer 2

Answer:

x = - 1/2

Step-by-step explanation:

Area of the square = s^2 = (2x + 2)^2 = 4x^2 + 8x + 4

Perimeter of the triangle = 3*s =  3(4/3)x = 4x

Difference = area of square - perimeter of triangle

Difference = 4x^2 + 8x + 4 - 4x = 3

Difference = 4x^2 + 4x + 4 = 3                  Subract 3 from both sides.

4x^2+ 4x + 4 - 3 = 0

4x^2 + 4x + 1 = 0                                        This factors.

(2x + 1)(2x + 1) = 0

Since they both are the same the value of one of them is the same as the value for both of them.

2x + 1 = 0

2x = - 1

2x/2 = - 1/2

x = - 1/2

So one value (the only value) of x = - 1/2
