To figure out how many hours it will take to drive from his home to his cousin house a student divides 289by 60 and estimate that it will take about 4.5 hours explain if you think it is a reasonable estimate.

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.

3x + 4y -25 =0 represents the amount of change sianna should recieve
