Question

15x+2x can be written as ____.

Answer 1

B.) (15 + 2)x because they both are getting multiplied by the value of x making it 17x.

Answer 2

15x+2x can be written as (15+2)x, since they have the same variable, so 15+2 can go inside the parentheses, and the x can go on the outside, meaning both 15 and 2 are multiplied by x.
Answer: (15+2)x
