We know, a number is divisible by 9 if the sum of digits is also divisible by 9.
Also, since A is an digit, so A is in between 0 to 9.
2+A+5+A+0+A+2 = 3A + 9
3A + 9 should be divisible by 9.
3A + 9 = 9n
A = (9n -9)/3
For n= 1 :
A = 0
For n=2 :
A = 3
For n= 3 :
A = 9
After this A > 9 which is not accepted.
Therefore, the digit A can be 0, 3 and 9 .
Hence, this is the required solution.
To find the scale factor, divide any part of the figure A'B'C'D' (the image) over the corresponding part of ABCD (preimage)
In this case, we know what CD and C'D' are, so we can say...
scale factor = (length of C'D')/(length of CD)
scale factor = (8)/(14)
scale factor = 4/7
Answer: 4/7
