Answer:


(g + f)(8) =133

Explanation:

Given


g(n) = 3n - 5


f(n) = n^2 + 50

Required


(g + f)(8)

This is calculated as:


(g + f)(n) =g(n) + f(n)

So, we have:


(g + f)(n) =3n - 5 + n^2 +50


Substitute 8 for n


(g + f)(8) =3*8 - 5 + 8^2 +50


(g + f)(8) =24 - 5 + 64 +50


(g + f)(8) =133
