Let's solve the expression:

$-10(9v - 4) + 10v$

Step-by-Step Solution:

1. Distribute $-10$ to both terms inside the parentheses:

$-10 \cdot 9v = -90v$ $-10 \cdot (-4) = 40$

This simplifies the expression to:

$-90v + 40 + 10v$

2. Combine like terms ($-90v$ and $10v$):

$-90v + 10v = -80v$

So the expression becomes:

$-80v + 40$

Final Answer:

$-80v + 40$
