Answer: 
Step-by-step explanation:
Since the center of dilation is not at the origin, we can use the following formula in order to find the coordinates of the vertices of the triangle D'E'F':

Where "O" is the center of dilation at (a,b) and "k" is the scale factor.
In this case you can identify that:

Therefore, susbtituting values into the formula shown above, you get that the coordinates ot the resulting triangle D'E'F, are the following:
Vertex D' → 
Vertex E' → 
Vertex F' →

Answer: 2 1/10
Step-by-step explanation:
21 : 10
Step 1: to write as a fraction= 21/10
2 1/10
Multiply the top and bottom by 2
6/14 = 12/28
now solving for the 2nd part is more difficult i would use cross multiply and divide . Multiply 6 and 12 which equals 72 then divide by 14 which will get you 5.142857 or 5 36/7= 71/14
