Answer:
2 sqrt(2x-1)
Step-by-step explanation:
f(x) = sqrt(x+7)
g(x) = 8x-11
f(g(x))=
Place g(x) in for x in the function f(x)
f(g(x)) = sqrt( 8x-11 +7)
= sqrt( 8x -4)
Factor out 4
= sqrt( 4(2x-1)
= 2 sqrt(2x-1)
9 I think this is the answer
Answer:
40k^2(3k - 2) + 48(3k - 2)
(40k^2 + 48)(3k - 2)
8(5k^2 + 6)(3k -2)
