12 - (16) + (-8) + (-6) - 2 - (10) + (-5)

-35

Step-by-step explanation:

Remove the parenthesis and evaulate:

12-16-8-6-2-10-5=-35

answer: idk

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.
