For the expression:

The denominator conjugate is 4 + 2i
When multiplied, the denominator is:

C = 2πr Divide both sides by 2r

= π Switch the sides to make it easier to read

Answer:
B
Step-by-step explanation:
The shape clearly is reflected across y axis and the x coordinates remain the same. We can see a change in the y coordinates and the shape has shifted 5 units down. Hence (x, y) -> (x, y-5) and then reflection across y axis is the answer
