Answer:
(x+1)^2
Step-by-step explanation:
(g ° f) (x) = g(f(x))
g ( f(x)) means that you are going to replace x in g(x) for f(x)
g(x) = x^2
f(x) = x+1
So you have to solve g(x) when x = x+1
g (x+1) = (x+1)^2

Answer:
6
Step-by-step explanation:
90
-------------------
10 + (3^2 - 4)
first we look at the parenthesis. take 3 to the second power, and it equals 9
90
------------------
10 + (9 - 4)
next, still in the parenthesis you subtract 4 from 9
90
--------------
10 + (5)
next add 10 plus 5
90
------- = 6
15
now divide 90 by 15 and you get your answer, 6
