Solve the absolute value inequality for y: 1.-2< |x|-y
2.4 ≥ -y +|2x-1|
3.-3y+6>|x-3|-6
4.2y<|6x|-1

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.

i think it would be 42cm
