step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
