Can you tell which of the following triangles are right and explain
your answer? the numbers represent the lengths of the sides:
9, 12, 15

12 because triangles will always have an odd number, and 12 is even
I think

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
