Question

If a and b are even integers and c is an odd integer, which of the following would be an odd integer? a + b + c ab - bc a x b x c b x c c (a + b)

Answer 1

A. a + b + c: a + b is even. Add c to even to get odd.
B. ab - bc: both products are even, so the difference is even
C. a x b x c: a and b are even, so the product is even
D. b x c: b is even, so the product is even
E. c(a + b): a + b is even, so the product is even
