Answer:

A. 4x-10

Step-by-step explanation:

We see that this is a rectangle. To find the perimeter, we do L+W+L+W. So in this case, we can do (x+2)+(x-7)+(x+2)+(x-7). We can also simplify this to   2(x+2)+2(x-7)

Combine like terms now.

Simplify this to:

2x+4+2x-14

Simplify further:

4x-10

Answer:

4x-10

Step-by-step 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
