I think it’s D) additional property of equality
Dilation:
The dilation factor is the length of image/preimage = 1.5
Thus
Q'R'/QR=1.5
Q'R'=1.5QR = 1.5 (5 cm) = 7.5 cm

Ok I will help you if I find out the answer.
Answer:
1/27
Step-by-step explanation:
The chance of getting X is ⅓. The chance of getting X then Y is ⅓², or ⅑. Finally, the chance of getting X, then Y, then Z is ⅓³, or 1/27
You do 28/100 which is 0.28
You then multiply this by 21
28/100 x 21 = 5.88
