Answer:
option B is correct, i.e. (f+g)(x) = x² + 3x - 5.
Step-by-step explanation:
Given f(x) = 3x + 1.
Given g(x) = x² - 6.
To find (f+g)(x).
The rule of Arithmetic of functions is:- (f+g)(x) = f(x) + g(x).
(f+g)(x) = (3x+1) + (x²-6).
(f+g)(x) = x² + 3x + 1 - 6.
(f+g)(x) = x² + 3x - 5.
Hence, option B is correct, i.e. (f+g)(x) = x² + 3x - 5.

Divide both sides by 2:
To find the other number, simply add 1 to 37 to get 38.
