Question

4.
Identify the correct statement
(A) If a, b, c are odd integers a + b + c cannot be zero
(B) If a, b, c are odd integers a² + b2 - C2# 0
(C) If a² + b2 = c2, then at least one of a, b, c is even, given that a, b, care intege
(D) If a2 + b2 = c2 where a, b, c are integers then c> a + b​

Answer 1

Step-by-step explanation:

Prove by contradiction that If a, b, and c are integers and a2 + b2 + = c2 then at least one of a and b is even. ... To add on to this, in case it's unclear, x,y and z are integers, and adding/subtracting integers can't result in 1/2. Therefore, a and b cannot both be odd
