14. 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)=14 2(15)=30 2(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
