A store is marking down the price of a television 25 percent from the original price of $250. Which expression can be used to find the marked down price? 250 dollars minus (0.25) (250)
250 dollars + (0.25) (250)
250 dollars minus (25) (250)
250 dollars + (25) (250)

A

Step-by-step explanation:

You're looking for the marked down price, which is less than the original 250, thus B and D is instantly knocked out. 25% as a decimal is expressed as .25, meaning that the only plausible answer in this scenario is A

answer: i think it is (1,-2)

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.
