Answer:
f(g(2)) = 102
Step-by-step explanation:
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
Answer:
56.43
Step-by-step explanation:
100% is the cost . With 8% tax added then total cost is 100 + 8 = 108%
multiply the cost by 108% for total cost
52.25 × 108% = 52.25 × = 56.43
