Miss Yang has bulletin boards of different sizes in her classroom. She wants to calculate how much border she needs for each one. The length of each bulletin board is 6 inches less than three times its width, w. Simplify w + 3w - 6 + w + 3w - 6 to find the formula for the penmeter of each of Miss Yang's bulletin boards.
