Answer:

Explanation:

Hello, by definition a perfect square can be written as
a^2 where a in a positive integer.

So, to answer the first question,
6^2 is a perfect square.

(a,b,c) is a Pythagorean triple means the following

a^2+b^2=c^2

Here, it means that

$x^2=20^2+21^2=841=29^2 \ \ \ so\\\\x=29$

Thank you.
