® 6(2x - 1)
© 6x(2-1)
-6x(2x - 1)
@ -6(-2x + 1)
® 6x(-2x + 1)

® 6(2x - 1); @ -6(-2x + 1)  

Step-by-step explanation:

12x - 6 = 6(2x- 1)  Factored out 6

12x - 6 = -6(-2x + 1)     Factored out -6

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.

step-by-step explanation:

i'm pretty sure it would take 20 hours because it's half the men so you multiply the number of hours it takes by 2
