[tex]\bf \begin{cases} g(x)=2x\\ h(x)=x^2+4 \end{cases}\qquad \begin{array}{llll} (h\circ g)(x)\implies h[~~g(x)~~]\\\\ (h\circ g)(-5)\implies h[~~g(-5)~~] \end{array}\\\\ -------------------------------\\\\ g(-5)=2(-5)\implies g(-5)=-10 \\\\\\ h[~~g(-5)~~]\implies h[~~-10~~]\implies h(-10)=(-10)^2+4 \\\\\\ h(-10)=100+4\implies h(-10)=104[/tex]
