Irrational
Step-by-step explanation:
When we take the square root of both sides, we get z = 0.141421... and since there are no fractions and the decimals go endlessly on, it is irrational.
C
You can use the pythagorean theorem.
5^2+4^2 =c^2 (or length of AB in this case)
25+16=c^2
41=c^2
c (or length of AB) = sqrt 40
