Math Help!

Look at the given triangles.
Large triangle left side says 4x+2 top says 7x+7 bottom days 5x-4. Small triangle left side says x+3 top says 2x-5 and bottom says
X+7.

a. Write an expression in simplest form for the perimeter of each triangle.

b. Write another expression in simplest form that shows the difference between the perimeter of the larger triangle and the perimeter of the smaller triangle.

c. Find the perimeter for each triangle when x = 3.

Please Help, I've been working on this all day and dont want to fail!

  1. Just do it.
    a.
    first triangle
    4x+2 + 7x+7 + 5x-4 = 16 x +5
    second triangle
    x+3 + 2x-5 + x+7 = you add

    b
    so subtract 16x+5 - ...x - ....

    c.
    first triangle
    16 (3) +5 = you do it
    now do triangle#2

    Ms. Sue
  5. 4x+2 + 7x+7 + 5x-4 = 16 x +5
    6x-14+9=16-21
    6x-5=-5
    +5 +5
    6x=0
    x=0

  6. x+3 + 2x-5 + x+7 = 35
    3x-16 +10 =35
    3x+-16=35
    +16=+16
    3x=51
    x=31
