which of the following is odd, if r is even and t is odd? Select:
A) rt	B) 5rt	C) 6r + 5t	D) 5r + 6t	E) 6(r^2)t
Just checking options (In case you have difficulty then choose values of r=2 and t=1)   r = even   t= Odd   A. rt = Even*Odd = EvenINCORRECT   B. 5rt = Odd*Even*Odd = EvenINCORRECT   E. 6(r^2)t = 6*(Even^2)*Odd = EvenINCORRECT   D. 5r + 6t = 5*Even + 6*Odd = Even+Even = EvenINCORRECT   C. 6r + 5t = 6*Even + 5*Odd = Even+Odd = Odd6r + 5tORRE6r + 5tT   Answer: option 6r + 5t
