To simplify the expression \(-10(-5f + 7f + 2) - f\), let's go through it step-by-step:

### Step 1: Simplify inside the parentheses
Combine like terms inside the parentheses:
\[
-5f + 7f + 2 = 2f + 2
\]
So, the expression becomes:
\[
-10(2f + 2) - f
\]

### Step 2: Distribute the \(-10\)
Now, distribute \(-10\) to both terms inside the parentheses:
\[
-10 \cdot 2f + (-10) \cdot 2 = -20f - 20
\]
Thus, the expression is now:
\[
-20f - 20 - f
\]

### Step 3: Combine like terms
Combine the \(f\)-terms:
\[
-20f - f = -21f
\]
So, the final simplified expression is:
\[
-21f - 20
\]

### Final Answer
\[
-21f - 20
\]
