The complete statement is:
The sequence of transformations applied to shape I that proves shape I is similar to shape II is a reflection across the y-axis, and then a dilation by a scale factor of 1.5.
From the figure, we can see that both shapes are on either sides of the vertical axis.
This means that:
Shape I is reflected across the y-axis.
Also, the measures of one of the corresponding sides of both shapes are:
Shape I = 2
Shape II = 3
So, the scale factor is:
[tex]\mathbf{k = \frac{Shape\ II}{Shape\ I}}[/tex]
This gives
[tex]\mathbf{k = \frac{3}{2}}[/tex]
[tex]\mathbf{k = 1.5}[/tex]
Hence, the scale factor is 1.5
