Question

rectangle wxyz was dilated using the rule d_z,\frac{12}{5}. what is wx? 8 units 10 units 12 units 14 units

Explanation:

Step1: Recall dilation formula

Length of image = Scale - factor×Length of pre - image

Step2: Identify scale factor and pre - image length

Scale factor is $\frac{12}{5}$, pre - image length $WX = 5$

Step3: Calculate $W'X'$

$W'X'=\frac{12}{5}\times5 = 12$

Answer:

12 units
