Question

Can someone help me please

Answer 1

`2x + 11 + 3x + 6 + 7x - 23`

`12x - 6`

Explanation:

The answer is 12x - 6 because you the add all the sides together for the perimeters.

Answer 2

perimeter is 12x-6

Explanation:

perimeter is the sum of all sides

3(x+2) + 2x+11 + 7x-23

distribute the 3 in the first term, then combine 'like terms'

3x+6 + 2x+11 + 7x-23

3x+2x+7x + 6+11+(-23)

12x-6
