Its C because both 5x and 2x have the same x at the end and their both considered like terms. so the answer would be C and if it was to be solved 5x+2x= 7x and 7+7x would be the final answer. since the 7 with no x has no x, it wouldnt have to be solved or simplified
Answer:
24-x=y (number of points scored in the first half)
if x equals 20, then we can rewrite the equation to
24-20=y
4=y
3.75
14.85
0.89
Those are the answers
Your answer would be 2x^2. Multiplying an x by an x makes it a squared variable.
