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.
To find the formula for the perimeter of Miss Yang's bulletin boards, we need to simplify the expression w + 3w - 6 + w + 3w - 6.
First, let's combine like terms:
w + 3w + w + 3w = 8w
Now, let's simplify the expression by combining the constant terms:
-6 - 6 = -12
Therefore, the simplified expression is:
8w - 12
The formula for the perimeter of each of Miss Yang's bulletin boards is 8w - 12.
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.
To find the formula for the perimeter of Miss Yang's bulletin boards, let's simplify the expression:
w + 3w - 6 + w + 3w - 6
Combining like terms, we have:
w + 3w + w + 3w - 6 - 6
Simplifying further, we get:
4w + 6w - 12
This can be further simplified as:
10w - 12
So, the formula for the perimeter of each of Miss Yang's bulletin boards is 10w - 12.
