Please help I don’t understand

2(x+1), or 2x+2 if they want an unfactored form.

Step-by-step explanation:

This problem says that the algebraic expression is sum of two consecutive even integers.  The first integer is x, which means that it's an even integer.  Since x is one of the integers it is even.  The next (consecutive) even integer would be x+2.

Therefore they want you to write;

x+(x+2), simplify

2x+2, factor if neccessary.

2(x+1) is your answer.
