Today, everything at a store is on sale. The store offers a 20% discount. Write an equation for this situation in terms of y.

The discount price will be 0.8X dollars.

Step-by-step explanation:

Price of an item = X dollars

Discount = 20%

Amount of discount = 20% of Price of item

Amount of discount =  

Price of item after discount = Price of item - Amount of discount

Price of item after discount = X-0.2X = 0.8X dollars

The discount price will be 0.8X dollars.

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.
