Let's simplify the expression: $-5(-10p + 8p - 5) - p - 5$.

Step 1: Simplify inside the parentheses

Inside the parentheses:
$-10p + 8p - 5$ simplifies to: $-2p - 5$

So, the expression now looks like: $-5(-2p - 5) - p - 5$

Step 2: Distribute the $-5$

Distribute $-5$ across $-2p - 5$: $-5(-2p) = 10p$ $-5(-5) = 25$

Now, the expression is: $10p + 25 - p - 5$

Step 3: Combine like terms

Combine the terms involving $p$ and the constant terms: $10p - p = 9p$ $25 - 5 = 20$

Thus, the simplified expression is: $9p + 20$
