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
Answer: Choice C) 6x
