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 + 18 D) P = x 2 - 10 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 OBJECTIVE 3
