3. consider this dilation. (a) is the image of the dilation a reduction or an enlargement of the original figure? explain. (b)what is the scale factor? explain.

Part a) The dilation is an enlargement

Part b) The scale factor is equal to 3

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is equal and this ratio is called the scale factor

Let

z----> the scale factor

In this problem

we have

substitute the values

The scale factor is greater than 1

therefore

The dilation is a enlargement

the solution is 12x-6y
