If p is an integer, what can be said about 2p? (a) 2p is an odd number (b) 2p is an even number
(b) 2p is an even number
Explanaiton: p ∈ Z, so 2p is an even integer. Even if p is a neg/pos# when mult by two it becomes even. ex: 2(7)=142(15)=302(4)=8. Also zero is neither negative or positive so dont worry about 2(0) because the question only asked if it would be neg/pos
