Hello from MrBillDoesMath!

Discussion:

In the order of operation, parentheses comes before subtraction so the expression equals

70 - 2 (5) - 4   =>                               as 40/8 = 5

= 70 - 10 - 4      

= 60 - 4

I believe the first respondent gave the same answer -- I just wanted to supply a few more steps for you

Thank you,

MrB

Step-by-step explanation:

f(x)=3x-8

g(x)=2x^2

f(g(5))=f(2×5^2)

=f(50)

=3×50-8

=150-8

=142
