Answer:

10

Step-by-step explanation:

( - 1, - 2 )

Let,

x1 = - 1

y1 = - 2

( - 9, 4 )

Let,

x2 = - 9

y2 = 4

Formula : -

Distance = √ [ ( x1 - x2 )² + ( y1 - y2 )² ]

Distance = √ [ ( - 1 - ( - 9 ) )² + ( - 2 - 4 )² ]

               = √ [ ( - 1 + 9 )² + ( - 6 )² ]

               = √ [ 8² + ( - 6 )² ]

               = √ [ 64 + 36 ]

               = √100

Distance = 10

I’m not quite sure how to answer this question.
Marina CMI [18]

When two shapes are mathematically similar, that means that all their sides are in a proportion.

We know the sieds of EH and AD, and so we can find the proportion of the shapes using these two sides.

EH/AD = 6/9 = 2/3

The ratio of EFGH to ABCD is 2:3

Now we have to find BC.

Becuase they're in proportion, we can form this equation:

\frac{8}{BC} = \frac{2}{3}

Cross multiply:

24 = 2*BC

Divide both sides by 2:

BC = 12 cm

Good luck!
