What is the 3rd step to solve 12(3x + 2) + 4 = 20

Step-by-step explanation:

The first step is distrubuting, 12 times 3x+2 = 36x+24.

The second step is adding 4 to 24 which is 28.

The third step is subtracting 38 from 20 which gives you -18.

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.
