To use the distributive property for the expression \( (4 \times 9) - (4 \times 1) \), we can factor out the 4:
\[ (4 \times 9) - (4 \times 1) = 4 \times (9 - 1) \]
So the expression can be rewritten as:
\[ (4 \times 9) - (4 \times 1) = 4 \times (9 - 1) \]
Thus, the blanks can be filled in as 4.
So the final statement is:
\[ (4 \times 9) - (4 \times 1) = 4 \times (9 - 1) \]
