Answer:
4x-10
Explanation:
The perimeter is the total around a shape. That means there will be two copies of each equation.
2(x+2)= 2x+4
2(x-7)= 2x-14
Add the two equations together and simplify.
2x+4+2x-14=
Add the like terms 2x together.
2x+2x= 4x
Keep doing the problem
4x+4-14
Solve 4-14 which equals -10
4x-10
