One board is one-third the length of another. Six times the sum of the nath of the short board and -10 is equal to the length of the longer board decreased by 11 inches. Find the length of the longer board.

Maybe the answer is 20mm. all i really did was just multiply, which is obvious.

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.
