Let -5 be n. Negative cubed is still a negative so it is a negative minus a negative number. So r is very negative. So s is positive because negative squared is positive. t is very (negative)^2 and that equals very positive. So the correct answer is
(D) r < s < t. (Note for this problem using logic is the simplest way to find the correct answer.)
