To find the missing values in the area model for the expression \(9(9n - 9)\), we can break it down using the distributive property.
The expression can be rewritten as:
\[
9(9n - 9) = 9 \cdot 9n - 9 \cdot 9
\]
Calculating each part:
1. \(9 \cdot 9n = 81n\)
2. \(9 \cdot 9 = 81\)
Thus, the expression simplifies to:
\[
81n - 81
\]
Therefore, in your area model:
- First part would be \(81n\)
- Second part would be \(-81\)
So the completed expression is:
\[
9(9n - 9) = 81n - 81
\]
The expression can be rewritten as:
\[
9(9n - 9) = 9 \cdot 9n - 9 \cdot 9
\]
Calculating each part:
1. \(9 \cdot 9n = 81n\)
2. \(9 \cdot 9 = 81\)
Thus, the expression simplifies to:
\[
81n - 81
\]
Therefore, in your area model:
- First part would be \(81n\)
- Second part would be \(-81\)
So the completed expression is:
\[
9(9n - 9) = 81n - 81
\]
