Step-by-step explanation:

I am going with A12x + 7yx = # of adult and y = # of childrenadults cost 12 and children cost 7 <

B doesn't make much senseu could say x was for girls and y for boys...but u already know how many there areso I am not sure what the x and y could stand for.

C does't make much sense eitherx would have to be red marbles and y would have to be green marbles...but just like B, u already know how many there areso not sure what x and y could stand for

D. wrongbecause the box containing x 7 oz packages and y 12 oz packages12x + 7yfor this one to be correct, it would have to have x 12 oz packages and y 7 oz packages

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.
