Answer:
I don't understand you're description, but 48 x 39 is 1872.
Step-by-step explanation:
Answer:
x = 5.5
Step-by-step explanation:
PM = MR
4x - 12 = -2x + 21 {add 2x to both the sides}
4x - 12 + 2x = -2x + 2x + 21
6x - 12 = 21 {Add 12 to both sides}
6x - 12 + 12 = 21 + 12
6x = 33
x = 33/6
x = 5.5
The dilation factor for the question should be 1/2 as per options
So
dilated lengths are
- 2(1/2)=1in
- 4/2=2in
- 1/2=0.5in
- 5/2=2.5in
