How can you find the side length of the square of Kendra wants exactly 1,000 feet

4x=1000 (4 sides on a square multiplied by x needs to be 4000). you could also just divide 1000 by 4 to get 250 for each side

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.
