A gym charges a $75 membership fee, and $12.50 per month. Write a sequence showing the charges for month 1, month 2, month
3, and so on.

Step-by-step explanation:

Month 1-$75+12.50=$87.50

Month 2-$87.50+$12.50=$100

Month 3-$100+$12.50=$112.50

Month 4-$112.50+$12.50=$125

This answer is correct only if you play for 4 months straight

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.
