![**Problem Statement:**
Suppose \( \mathbf{u}, \mathbf{v} \) are vectors in \(\mathbb{R}^n\) satisfying:
\[
\|\mathbf{u}\| = 3, \quad \|\mathbf{v}\| = 4, \quad \text{and} \quad \mathbf{u} \cdot \mathbf{v} = -1
\]
Determine \( (3\mathbf{u} + 2\mathbf{v}) \cdot (\mathbf{u} - \mathbf{v}) \).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F46c0fb16-724b-4726-818c-9156075ac6cc%2F62b08e38-1b15-4fa6-9acd-7fa187fa843f%2Fsbfpxxk_processed.jpeg&w=3840&q=75)
