Question
**Problem Statement:**

Suppose that \( 9(g(x))^3 + 10x = 9x^2g(x) + 40 \), and that \( g(4) = -4 \). Find \( g'(4) \).

**Solution:**

To solve this problem, we need to differentiate both sides of the given equation with respect to \( x \) and then find \( g'(4) \) using the given condition. 

1. Differentiate the equation \( 9(g(x))^3 + 10x = 9x^2g(x) + 40 \) with respect to \( x \).
2. Use the chain rule to differentiate \( (g(x))^3 \) and the product rule for \( x^2g(x) \).
3. Substitute \( g(4) = -4 \) into the derivative equation and solve for \( g'(4) \).

Following these steps will yield the value of \( g'(4) \).
