To find the formula for the perimeter, we need to simplify the expression:
w + 3w - 6 + w + 3w - 6.
Combining like terms, we have:
8w - 12.
Therefore, the formula for the perimeter of each bulletin board is 8w - 12.
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 perimeter of each of Miss Yang’s bulletin boards.
