Which expression is equivalent to -6(-2/3+2x)

-4 - 12x
-4 + 2x
4 - 12x
4 + 12x

-12x+4

Step-by-step explanation:

-6(-2/3+2x)

=(-6)(-2/3)+(-6)(2x)

=4 -12x

=-12x+4

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.
