Answer:

B. 25

Step-by-step explanation:

In order to find out the value of x + 2, you need to know what x is.  Let's solve for it then sub it back in to evaluate the expression.

3(x+2)=5(x-8) distributes out to give you

3x + 6 = 5x - 40.  Get like terms together on opposite sides of the equals sign:

46 = 2x and divide to get x = 23.  Now that we know that x = 23, that means that x + 2 is the same as 23 + 2 which is 25.
