The answer is L = 59 + 2(d). If we plug in our numbers, we will get L = 59 + 2(32). 2*32 is 64, and if you add 59 you get 123 miles.
This isn’t apart of the question, but 59 would be the y-intercept. 2 miles per day (2/1) is the slope.
#5 is 96 because it is congruent to the one on top
V=LWH
if each is doubled
V=2L2W2H
V=2*2*2*LWH
V=8LWH
volume is multiplied by 8
