A car dealership is trying to sell all of the cars that are on the lot. If there are 675 cars on the lot and they sell 45 cars per week, how many weeks will it take for the number of cars on the lot to be less than 65?

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
