**Problem Statement:**

If the marginal revenue for ski gloves is given by

\[
MR = \frac{-12}{(2x + 5)^2} + 20
\]

and \( R(0) = 0 \), find the revenue function.

**Revenue Function:**

To find the revenue function \( R(x) \), you will need to integrate the marginal revenue function \( MR \).

**Solution Steps:**

1. **Integrating the Marginal Revenue:**
   
   The given marginal revenue function is:

   \[
   MR = \frac{-12}{(2x + 5)^2} + 20
   \]

   To find the revenue function \( R(x) \), integrate the marginal revenue with respect to \( x \):

   \[
   R(x) = \int \left( \frac{-12}{(2x + 5)^2} + 20 \right) \, dx
   \]

2. **Applying Initial Condition:**

   Given \( R(0) = 0 \), use this condition to solve for the constant of integration after performing the integration.

3. **Result:**

   After performing the integration and applying the initial condition, write the final form of the revenue function \( R(x) \).

Fill in the expression into the box labeled \( R(x) = \) once the integration is complete and the function is determined.

**Note:** Detailed integration calculations are needed to find the specific form of \( R(x) \).
