Answer:
The correct answer is Choice C.
Explanation:
When figuring out the perimeter, we need to count the number of sides. There are 8 sides in total. 5 sides have length labeled 'x' . 2 sides have the length labeled 'y' . Only 1 side has the length labeled 'z' .
In order to put that into an expression, just add the sides up.
5 sides of z + 2 sides of y + 1 side of z
Therefore, the expression that represents the perimeter of the figure is 5x + 2y + z.
