Question

it is multiple choice and I can't figure it out and it is supposed to have two boxes checked

Answer 1

From the picture, all the sides have the same length, then

2(x + 4) = 3x - 1

Distributing

2(x) + 2(4) = 3x - 1

2x + 8 = 3x - 1

Subtracting 2x at both sides,

2x + 8 -2x = 3x - 1 - 2x

8 = x - 1

Adding 1 at both sides,

8 + 1 = x - 1 + 1

9 = x

Therefore, the length of the sides is

side length = 3x - 1

side length = 3(9) - 1

side length = 27 - 1

side length = 26
