63. An art teacher gave each group of students packages of clay. If there were 6 students in each group, how many packages of clay would the teacher have used for a class of 30 students?

5

Step-by-step explanation:

you divide 6/30=5

hope this helps

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.
