Answer: \(f(g(x)) = 12x + 26\)

Explanation:

To find \(f(g(x))\), you'll first substitute the expression for \(g(x)\) into \(f(x)\). Here are the steps:

1. Start with \(f(x)\):

\[f(x) = 6x - 4\]

2. Now, substitute \(g(x)\) into \(f(x)\):

\[f(g(x)) = 6(g(x)) - 4\]

3. Replace \(g(x)\) with its expression:

\[f(g(x)) = 6(2x + 5) - 4\]

4. Distribute the 6 into the terms inside the parentheses:

\[f(g(x)) = 12x + 30 - 4\]

5. Simplify the expression:

\[f(g(x)) = 12x + 26\]

So, \(f(g(x)) = 12x + 26\).
