A construction crew is lengthening a road that originally measured 52 miles. The crew is adding one mile to the road each day.

Let L be the length (in miles) after D days of construction.
write an equation relating L to D. then use this of find the length of the road after 26 days.

The equation relating L to D can be expressed as:

L = 52 + D

To find the length of the road after 26 days, we substitute D = 26 into the equation:
L = 52 + 26
L = 78

Therefore, the length of the road after 26 days of construction is 78 miles.
