What does x=? I'm really not sure about this.

9

Step-by-step explanation:

For this, we need to know the scale factor first. We can do that by looking at a same side of the two shapes.

CD = 2 and ML = 3.6

3.6 / 2 = 1.8

just to confirm, let's take MN = 7.2 and DE = 4

7.2 / 4 = 1.8

So now we know the scale factor is 1.8

Now to figure out x, we just need to use BA = 5

and because the scale factor is 1.8

so we just need to do: 5 * 1.8 = 9
