The expression can be simplified step by step. Starting with the original expression:
\[
-0.4r - 3(-9r - 6)
\]
1. Distribute the -3 across the parentheses:
\[
-0.4r + 27r + 18
\]
2. Combine like terms:
\[
(-0.4r + 27r) + 18 = (26.6r) + 18
\]
So, the simplified expression is:
\[
26.6r + 18
\]
\[
-0.4r - 3(-9r - 6)
