To expand the expression \(-5.6(9b - 12)\), we can distribute \(-5.6\) to both terms inside the parentheses:
- \(-5.6 \times 9b = -50.4b\)
- \(-5.6 \times -12 = 67.2\)
Putting it all together, the expanded expression is:
\(-50.4b + 67.2\)
So, filling in the blanks, the completed expression is:
-50.4b + 67.2
