If x is a positive integer, which of the following must be odd? Choose the correct choice from the following answers: A) x+1 B) x^2+x C) x^2+x+9 D) x^2−1 E) 3x^2−3
A. X+1 = can be odd or even. Since O + O =E or E + O = O B. X^2 + X = X(X+1). Since from the above derivation we already know the term X+1 can be Odd or Even, directly substitute here. X(ODD) = Even (When X is Even) or X(EVEN) = EVEN [When X is ODD] C. Here's the answer. Since we know the term x^2 + X can always ta...
