If x is even and y is odd, which of the following is odd?  Select the correct option
A) xy	B) 5xy	C) 6(x^2)y	D) 5x + 6y	E) 6x + 5y
Just checking options (In case you have difficulty then choose values of r=2 and t=1)   x = even   y= Odd   A. xy = Even*Odd = EvenINCORRECT   B. 5xy = Odd*Even*Odd = EvenINCORRECT   C. 6(x^2)y = 6*(Even^2)*Odd = EvenINCORRECT   D. 5x + 6y = 5*Even + 6*Odd = Even+Even = EvenINCORRECT   E. 6x + 5y = 6*6x + 5yven + 5*Odd = 6x + 5yven+Odd = OddCORR6x + 5yCT   Answer: option 6x + 5y
