Aconstruction crew is lengthening a road. the road started with a length of 51 miles, and the crew is adding 4 miles to the road each day. let l represent the total length of the road (in miles), and let d represent the number of days the crew has worked. write an equation relating l to
d. then use this equation to find the total length of the road after the crew has worked 37 days.

L = total lengh, D = number of days

L = 4D + 51 <== ur equation

after 37 days...D = 37
L = 4(37) + 51
L = 148 + 51
L = 199 miles <==

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.
