figure a is dilated to form figure d. what is the scale factor of the dilation? scale factor =

Explanation:

Step1: Identify corresponding side lengths

Find a side length of figure \(A\) and the corresponding side length of figure \(D\). Let's take the horizontal side. The horizontal side of figure \(A\) is \(1\) unit. The corresponding horizontal side of figure \(D\) is \(4\) units.

Step2: Calculate the scale factor

The formula for the scale factor \(k\) of a dilation is \(k=\frac{\text{length of side in image}}{\text{length of side in pre - image}}\). So \(k = \frac{4}{1}\)

Answer:

\(4\)
