WHat is the answer to this?

0.9

Step-by-step explanation:

First, convert them all into fractions:

Now, we have:

Cross multiply:

On the left, distribute. On the right, notice that the 3 in the denominator and the coefficient 3 cancel:

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
