Answer:
g(-3)+13= -8
f(h+9)=2h+12
f(7)+9=17
f(3)+g(2)=-6
3(g(b)+2)=3b-6b²+6
Step-by-step explanation:
f(x)=2x-6 and g(x)=x-2x²
g(-3)+13
((-3)-2(-3)²)+13
(-3-2(9))+13
-3-18+13
-8
f(h+9)
2(h+9)-6
2h+18-6
2h+12
f(7)+9
(2(7)-6)+9
14-6+9
17
f(3)+g(2)
(2(3)-6)+(2-2(2²))
(6-6)+(2-2(4))
0+2-8
-6
3(g(b)+2)
3((b-2b²)+2)
3b-6b²+6
The solution is 6-->4-->9-->7-->1
