### Properties of Determinants

Consider the following determinant problem:

\[ 
\begin{vmatrix}
-10 & s & s \\
35 & -20 & 25 \\
0 & 15 & 30 \\
\end{vmatrix}
 = s^3 
\begin{vmatrix}
-2 & 1 & 1 \\
7 & -4 & s \\
0 & 3 & 6 \\
\end{vmatrix}
\]

This problem illustrates the properties of determinants, specifically how they change with scalar multiplication and matrix operations. 

**Explanation of each matrix:**

1. **First Matrix:**
   - Row 1: `-10`, `s`, `s`
   - Row 2: `35`, `-20`, `25`
   - Row 3: `0`, `15`, `30`

   This matrix shows real numbers and variables which can affect the determinant calculation, dependent on the scalar \( s \).

2. **Second Matrix:**
   - Row 1: `-2`, `1`, `1`
   - Row 2: `7`, `-4`, `s`
   - Row 3: `0`, `3`, `6`

   The second matrix is multiplied by \( s^3 \), indicating the effect of scaling by \( s \).

This example demonstrates how modifying elements in a matrix or scaling by a factor like \( s^3 \) will affect the outcome of the determinant.
