Please, post the instructions along with your question, and if possible share the question in symbolic form, not in words.
Do you mean Question #5? By (2) x cube, do you mean 2x^3?
I strongly suggest that you use lots of parentheses ( ) to show how your numbers are grouped, and not to use " x " to denote multiplication (use " * " for that, please.
If only you'll clear this up, I'd be happy to help.
I will assume that your post is 2x^3 - 3(9x-5)^2.
Then 2x^3 - 3(81x - 90x + 25). Does this have any resemblance to what you wanted me to see in your post?

Answer:
C. 88
Explanation:
f(x) = 4x + 8 || g(x) = x² + x
fg( -5 )
go from right to left in such function problems.
replace x with [ -5 ]
f( (-5)² -5)
f(20)
[ replace x with 20 ]
4(20) + 8
80 + 8
88
3? i think so i don’t know if it’s right
