Answer:
k = 2
Explanation:
A dilation is a type of transformation that changes the size of the pre-image without changing its shape.
The scale factor of dilation is found by using the ratio of new length to the original length.
Therefore, to find the scale factor of a dilation, divide the measure of a side of the image by the measure of the corresponding side of the pre-image.
Therefore, the correct calculation for finding the scale factor of the dilation is:
