If the perimeter is 39 what you have to do is 39 - 8.5 - 8.5 that will give you 22 and divide 22/2 and that gives you 11. So 11 is the length
A rotation on its axis of 180 degrees
Answer: 
Step-by-step explanation:
Some transformations for a function f(x) are shown below:
If
, the function is translated up "k" units.
If
, the function is translated down "k" units.
If
, the function is reflected across the x-axis.
If
, the function is reflected across the y-axis.
Therefore, knowing those transformations and given the exponential parent function:

If it is reflected across the y-axis and the it is translated down 4 units, we can determine that the resulting function is:

Ling JM is also 23 centimeters because line LJ and JM are a line but broken into two segments
