Given the following functions f(x) and g(x), solve (f+g)(5) and select the correct answer below:
f(x) = 8x - 13
g(x) = X-9

options:
23
27
31
40

65

step-by-step explanation:

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
