Acooking class want to use up 8 cups of buttermilk and 11 eggs by baking rolls and muffins to freeze. a batch of rolls uses 2 cups of buttermilk and 3 eggs. a batch of muffins uses 1 cup of buttermilk and 1 egg. write a system of equations for this situation.

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.
