Which expression represents the composition f(g(h( for the functions below?

f(x) = 2x + 1
g(x) = 4x^2
h(x) = x^2

4x^4

8x^2 + 1
(8x^2 + 1)^2

The first few steps in solving the quadratic equation 9x2 + 49x = 22 ? 5x by completing the square are shown. 9x2 + 49x = 22 ? 5x 9x2 + 54x = 22 9(x2 + 6x) = 22 which is the best step to do next to solve the equation by completing the square? 9(x2 + 6x + 3) = 25 9(x2 + 6x + 3) = 49 9(x2 + 6x + 9) = 31 9(x2 + 6x + 9) = 103
