Question

Can someone help me and tell me what I got wrong

Answer 1

I'm not sure what you did at first, but here's how I solved it:

7(3+3)-9

7(6)-9

42-9

=33

i can't see your original answer, so i can't tell you specifically what went wrong, but i hope that helps!

Answer 2

Answer: 33

Step-by-step explanation:

f(a)=7(a+3)-9

f(3)=7(3+3)-9

f(3)=7(6)-9

f(3)=42-9

f(3)=33
