Which does not have a perimeter of 8x+8.

Figure 1 does not have perimeter 8x +8

Step-by-step explanation:

Perimeter of  shape is the sum of all the sides.

Perimeter of figure 1 = 2x +2 + x + 2x + 2 +x

                                  = 2x + 2x + x + x + 2 + 2   {Combine like terms}

                                  =6x + 4

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
