Miss Yang has bulletin boards of different sizes in her classroom. She wants to calcute how much border she needs for each one. The length of each bulietin board is 6 inches less than three times its width, a. Simplify w + 3w - 6 + w ÷ 3w - 6 to find the formula for the perimeter of each of Miss Yang's bulletin boards. (1 point)
To simplify w + 3w - 6 + w ÷ 3w - 6, we can first combine like terms: 4w - 6 + w ÷ 3w - 6.
Next, we perform the division: (4w - 6) + (w(1/3)) + (w - 6).
Finally, we simplify further: 4w - 6 + (1/3)w + w - 6.
This can be combined into a single expression: (4w + (1/3)w + w) - 6 - 6.
Combining like terms, we have: (5 1/3)w - 12.
The simplified formula for the perimeter of each of Miss Yang's bulletin boards is (5 1/3)w - 12.
