Apply the distributive property to rewrite 3(2-b).

3·2 - 3·b = 6 - 3b

Step-by-step explanation:

You "distribute" the 3 over the 2 and the -b.

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.
