Answer:
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.
