Assume that r and s are particular integers. 1. Is 4rs even? Prove it or give a counterexample. 2. Is 6r + 4s^2 + 3 odd? Prove it or give a counterexample. 3. If r and s are both positive integers, is r^2 + 2rs + s^2 composite?

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5
