Is 5, 12, 14 a pythagorean triple ? Show why or why not?

No

Step-by-step explanation:

Let's test these values using the Pythagorean Theorem.

a^2+b^2=c^2

where a and b are the legs and c is the hypotenuse.

a and b are the legs, or the shorter sides. 5 and 12 are the shorter sides, so they are a and b.

c is the hypotenuse, or the longest side. 14 is the longest side, so it is c.

5^2+12^2=14^2

Evaluate all the exponents

25+144=196

Add 25 and 144

169=196

169196

169 is not equal to 196, so 5, 12 and 14 cannot be a Pythagorean Triple

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315
