If m and n are even integers, which of the following is an odd integer?  Pick one:
A) mn + 2
B) m(n − 1)
C) m(m + 5)
D) 3m + 4n
E) (m + 3)(n − 1)
If m and n are even integers, then:   A. mn + 2: even + even = even   B. m(n − 1): even(odd) = even   C. m(m + 5): even(odd) = even   D. 3m + 4n: even + even = even   E. (m + 3)(n − 1): (odd)(odd) = odd.   Answer is (m + 3)(n − 1).
