Which expression gives the perimeter of the regular hexagon shown below?

Each side is x units long. There are 6 sides. So we add up all the sides to get the perimeter.
x+x+x   +   x+x+x
there are six copies of x being added

Simplifying that expression above leads to 6*x or simply 6x. Multiplication is a shortcut for repeated addition. Instead of saying 2+2+2+2, we can write 4*2

Choice C) 6x
