A construction crew is lengthening a road. The road started with a length of 57 miles, and the crew is adding 2 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 38 days.
