g(x)=x^2-1
f(g(X))=5 sqrt(x^2-1+1)-2
5 sqrt(x^2)-2
:sqrt cancel the square
5x-2
Answer: 4
Step-by-step explanation:
If the foot-long sandwhich is 4 feet long, and is cut into parts that are each 1 foot long, then we need to divide 4 by 1.
4 ÷ 1 = 4, so there will be 4 servings after the sandwich is cut.

Answer:
(2x-7y) (2x+7y)
Step-by-step explanation:
4x^2−49y^2
This is the difference of squares
a^2 - b^2 = (a-b) (a+b)
a^2 =4x^2 so a = 2x
b^2 = 49y^2 so b =7y
4x^2−49y^2 = (2x-7y) (2x+7y)
