If x is a positive even number, then each of the following is odd EXCEPT  Choose the correct choice from the following options:  A) (x + 3)(x + 5)  B) x^2 + 5  C) x^2 + 6x + 9  D) 3x^2 + 4  E) 5(x + 3)
lets see the choices..   A. (x + 3)(x + 5)   We have two terms with x and each is added with a odd number..   each bracket becomes odd and Odd*Odd=Odd   B. x^2 + 5   here we are adding an Odd number to even.. so E + O=O   C. x^2 + 6x + 9   here we are again adding an Odd number to even.. so E +E + O=O   D. 3x^2 + 4   here we are adding an Even number to even.. so E + E=E..   so this is our answer   E. 5(x + 3)   again O*O=O   ANSWER:3x^2 + 4
