Miss Yang has bulletin board of different sizes in classroom 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 premier of each bulletin board
To find the perimeter of each bulletin board, we need to first simplify the expression w+3w-6+w+3w-6.
Combining like terms, we have:
w + 3w + w + 3w - 6 - 6
This simplifies to:
8w -12
Therefore, the perimeter of each bulletin board is 8w - 12.
