Step-by-step explanation:

  • 2

The perimer of a traingle is the saum of its sides

P = 2(3x+7) + 2(2x+2)

  • 3
  1. P= 2(3x+7) + 2*(2x+2)   multiply (3x+7) and (2x+2) by 2
  2. P= 6x+14+4x+4             add the khown values together
  3. P=6x+4x+18                  add the terms with the variable x
  4. P= 10x+18
10x+20 is the answer.
Since all you have to do is just add the sides lengths.
