Answer:

$g(g(x)) = {x}^(4) + 14 {x}^(2) + 56$

h(h(x)) = x

Explanation:

$g(x) = {x}^(2) + 7$

$g(g(x)) = {( {x}^(2) + 7)}^(2) + 7$

$g(g(x)) = {x}^(4) + 14 {x}^(2) + 49 + 7 = {x}^(4) + 14 {x}^(2) + 56$

h(x) = (5)/(9x)

h(h(x)) = h( (5)/(9x) )

h(h(x)) = (5)/(9( (5)/(9x) )) = (5)/( (5)/(x) ) = 5( (x)/(5)) = x
