Let's simplify the expression step by step:
The expression is:
\[
-3(4 - 9) + 6 - 2(-8 + 5)
\]
1. Start with the parentheses:
- Calculate \(4 - 9\):
\[
4 - 9 = -5
\]
- Calculate \(-8 + 5\):
\[
-8 + 5 = -3
\]
2. Substitute these results back into the expression:
\[
-3(-5) + 6 - 2(-3)
\]
3. Simplify each term:
- Calculate \(-3(-5)\):
\[
-3(-5) = 15
\]
- Calculate \(-2(-3)\):
\[
-2(-3) = 6
\]
4. Substitute these values back in:
\[
15 + 6 + 6
\]
5. Now, add them together:
\[
15 + 6 = 21
\]
\[
21 + 6 = 27
\]
Thus, the final simplified value is:
\[
\boxed{27}
\]
So the correct option is \(c) 27\).
