Answer: 7x + 14
Step-by-step explanation:
5x + 2(x + 7)
First, we use distributive property to distribute the 2 to the x and the 7. We're left with this expression:
5x + 2x + 14
We can combine 5x and 2x to get 7x
7x + 14
We cannot do anything else with this expression and it is thus is simplest form.
