How do you solve this step by step?

x = -1

Step-by-step explanation:

since the 23 is positive you have to subtract it on both sides . which would give you -4x =4

then divide -4 on each side and you should get x = -1

a positive divided by a negative is always negative.

you answer is a

step-by-step explanation:

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.
