I got 3; M=-4 so you plug that in and get -4^2+5(-4)+7
-4 times -4=16
5 times -4=-20
16+(-20)=-4
-4+7=3
<span>f(x) = x^3 </span>
<span>g(x) = 1+x^2 </span>
<span>Therefore: </span>
<span>H(x) = f[g(x)] = (1+x^2)^3 </span>
3. 49
4. 26
u just add up all the sides then subtract it from 180
do it step by step will it work yes
