$86 a - 25$

#### Explanation:

We are given $11 + 6 \left(15 a - 6\right) - 4 a$

First, let's multiply the $6$ to what's inside the parenthesis:

$11 + 6 \left(15 a - 6\right) - 4 a$

$11 + \left(6\right) 15 a - 6 \left(6\right) - 4 a$

$11 + 90 a - 36 - 4 a$

Now, let's simplify:

$11 + 90 a - 36 - 4 a$

$\left(11 - 36\right) + \left(90 a - 4 a\right) = - 25 + 86 a$

So, after simplification we obtain:

$86 a - 25$
