Answer:
7(2x+16)
Step-by-step explanation:
first, we look at the part where it says the sum of twice a number and 16
let's represent the number by using x. since it says twice a number, that would mean 2x.
when it says the sum of twice a number and 16, this means that we have to add them, so we would get 2x+16.
finally, in the beginning it says seven times the sum of twice a number and x, which would mean that we would have to multiple 2x+16 by 7.
answer:
7(2x+16)
Answer:
[X-1]^3
Step-by-step explanation:
X-3^3+8
8 is 2^3
X-3^3+ 2^3
[(X-3)+2)]^3 = [X-3+2]^3 = [X-1]^3
