Step-by-step explanation:

he needs one box

he needs 4 individuals 1.39×4=5.56

6 x.59=3.54

5.56+3.54=9.1

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
