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 it’s width ,w. Simplify w + 3w - 6 + w +3w - 6 to find the formula for the perimeter of each of miss yangs bulletin boards
The formula for the perimeter of each of Miss Yang's bulletin boards can be simplified as:
P = w + 3w - 6 + w + 3w - 6
P = 8w - 12
