Answer:

9x² -5

Step-by-step explanation:

(f○g)(x) means f(g(x))

Put the definition of g(x) in place of x in the definition of f(x):

f(g(x)) = f(x²) = 9(x²) - 5

(f○g)(x) = 9x² - 5

A container has 3 apple juice boxes, 4 grape juice boxes and 5 orange juice boxes. Alex picks one juice box, drinks it and then

Hey!

Grape over total: $\frac{4}{12}$

After he drinks 1, there will be 1 less. That means it will be over 11

Orange over total: $\frac{5}{11}$

Now multiply the fractions

$\frac{4}{12} \times \frac{5}{11} = \frac{20}{132} \rightarrow \frac{10}{66} \rightarrow \frac{5}{33}$

That means the probability is: $\frac{5}{33}$

Good luck and hope this helps! :)
