Question

triangle qrs was dilated using the dilation rule ( d_{p,4} ). what is ( pr )? 15 units 12 units 9 units 6 units

Explanation:

Step1: Recall the dilation formula

The formula for dilation is \(PR'=k\times PR\), where \(k\) is the scale factor. Here, the scale factor \(k = 4\) (from the dilation rule \(D_{P,4}\)) and \(PR = 3\) units.

Step2: Calculate \(PR'\)

Substitute the values into the formula: \(PR'=4\times3\).

Answer:

12 units
