Alex and Brandon bought candy and popcorn at the movie theater. Alex bought 2 tubs of popcorn and 3 boxes of candy for $19.50. Brandon bought 2 tubs of popcorn and 5 boxes of candy for
$22.50. If all the popcorn costs the same and all the candy costs the same, how much did one tub of
popcorn cost?

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1

could you reply to this with the question so i can ?
