Which of the following sets of numbers could not represent the three sides of a triangle? A {15,21,33} B {13,27,38} C {15,27,43} D {6,15,20

step-by-step explanation:

goog be able to you with that maybe

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
