Chris is Tom's sibling

Prove or Disprove each of these propositions.

a) If p and q are prime numbers, then pq+1 is a prime number.

b) If x and y are positive integers with x>y+1, then x2 - y2 is not prime.

c) If Tom has at most n brothers and Chris is Tom's sibling, then Chris has at most n brothers.

d) If a and b are positive integers, then square root(a2+b2) = a +b.

e) Every even number can be written as the sum of an odd number and a perfect square.

f) The product of a multiple of 6 and a multiple of 10 is a multiple of 60.

Please show the steps as I am trying to study for an exam and I am bad at proofs!
