If h of x is equal to x minus 7 and g of x is equal to x squared , which expression is equivalent to open paren g circ h close paren times 5 ?

The composition (g ∘ h)(5) means first evaluate h at 5, then apply g to that result. Since h(5) = 5 − 7 and g(x) = x², the expression is (5 − 7)². That matches “(5 − 7) squared.”
