ANSWER
C) 5.1 units
EXPLANATION
The coordinates of A are (5,2).
If this point is translated 1 unit to the left and 5 units down to create point A'.
Then A' has coordinates
The distance between A and A' is calculated using the distance formula,
We round to the nearest tenth to obtain,
The measurement that is closed to the distance is 5.1 units
