1. THE perimeter is the distance around
3-A) A hexagon has 3 sides of length x -2 and 3 sides of length x + 5. What is the perimeter, P, of the hexagon in terms of x?
A) P =2x + 3 B) P =6x + 3 C) P =12x D) P = x E) P =6x + 9
E IS THE RIGHT EXPRESSION!
THE perimeter is the distance around
THE HEXAGON:
x + 5
x + 5
x -2
THE HEXAGON
x + 5
x -2 -6 15
x -2
6x+15-6 =
6x + 9
P = (x + 5)+(x + 5)+(x + 5) +(x -2)+(x -2)+(x -2) = 6x
