Without an actual question, it's difficult to provide a complete answer, but I can help you understand the format of this expression. In math, letters and symbols can be used to represent different values or operations.
For example, if Angela needs to fence in a rectangular garden with length "L" and width "W," the total amount of fence she needs would be:
2L + 2W
This expression represents the total length of fence needed to surround the garden, which is equal to twice the length plus twice the width (since the garden has two lengths and two widths).
Similarly, if Angela needs to build a circular fence around a garden with radius "r," the total amount of fence needed would be:
2πr
This expression represents the circumference of the circle, which is equal to 2 times pi (π, a mathematical constant) times the radius.
I hope this helps! Let me know if you have any other questions.
