On this question, we can use the order of operations. ( pemdas )
First, we must fill in the missing numbers.
9*21 + (3*3)21 + 12
Start in the parentheses.
(3*3)21 = 9*21 = 189
189+189+12
The rest is just addition now!
189+189+12=390
390 is the correct answer.
Answer:
f(7) = 2
Step-by-step explanation:

f(7) (3 + 6) = 18
f(7) x (9) = 18
f(7) = 2
