You're just simply multiplying them by 2 because the scale factor being applied is 2. So..
P' Q' = 4 cm
A' B' = 3 cm
M' N' = 6 cm
Answer: Associative property
Step-by-step explanation:
Use order of operations for this
4x+17=23
Move the 17 to the 23
4x=23-17
Then move the 4 over leaving the x by itself
X=6/4
X=1.5
X/5120=20/100
x/5120=1/5
5120/5=1024
1024+5120=6144
6144 is the answer.
