  13. Blue: P=4x +2+7x +7+5x-4 --> 16x +9-4=16x +5
    Red: P=x+3+2x - 5 + x + 7 --> 4x + 10 - 5 = 4x + 5

    Difference between the perimeter:
    (16x + 5) - (4x + 5) = 16x + 5 - 4x - 5 = 12x

    Perimeter when x = 3
    Blue : 16x + 5 ⇒ 16(3) + 5 = 48 + 5 = 53
    Red: 4x + 5 ⇒ 4(3) + 5 = 12 + 5 = 17

  15. @children in my basement, the formula for a right triangle is a^2 + b^2 = c^2, so how is 53 and 17 an answer? Just curious, Im stuck on the question.

  16. @Gotta run, i think it's bc the question didn't specifically ask for the formula of a right triangle to be used (?) so that's why it equals those perimeters

  17. @Gotta run, that formula is not used for this situation. For this situation you are just adding up the sides. I am pretty positive that children is correct.
