Answer:
5. is 3 bc 4 ft. - 1 ft.
6. is 2 bc 3ft. - 1ft.
8. and 7. is 20 cm bc 40cm + 40cm = 80cm - 60cm = 20cm
9. is 18 + 18 = 36
10. is 48 bc 24 + 24=48
11. is 15 bc 45 - 30 = 15
Step-by-step explanation:
first one is 36
A
f(g(2)) = 102
f(x) and f(g(2))
As we can see, we can find g(2) and substitute this value into
f(x)=x² + 2x + 3 instead of x.
g(x) = x² + 5, g(2) = 2² + 5 = 9
f(x)=x² + 2x + 3
f(9)=9² + 2*9 + 3= 102
yes yes spare
H=15
Do the problem backwards 17-2=?
17-2=15 so 15+2=17 so h=15
