**Finding the Integrals for the Center of Mass of a Thin Plate:**

Given the region bounded below by the parabola \(y = x^2\) and above by the line \(y = x\), and assuming the plate's density is \(\delta(x) = 12x\), we aim to set up the integrals for the center of mass. Do not solve these integrals.

---

**Formulas:**

- **Moment about the x-axis (\( M_x \))**
\[ M_x = \int \int y \delta(x) \, dA \]

- **Moment about the y-axis (\( M_y \))**
\[ M_y = \int \int x \delta(x) \, dA \]

- **Mass (\( M \))**
\[ M = \int \int \delta(x) \, dA \]

---

**Integrals Setup:**

1. **Moment about the x-axis (\( M_x \))**

   \[
   M_x = 
   \]

   \[
   \int_{a}^{b} \int_{g(x)}^{f(x)} y \delta(x) \, dy \, dx
   \]

2. **Moment about the y-axis (\( M_y \))**

   \[
   M_y = 
   \]

   \[
   \int_{a}^{b} \int_{g(x)}^{f(x)} x \delta(x) \, dy \, dx
   \]

3. **Mass (\( M \))**

   \[
   M = 
   \]

   \[
   \int_{a}^{b} \int_{g(x)}^{f(x)} \delta(x) \, dy \, dx
   \]

**Details of the Region:**

1. The parabola is represented by \( y = x^2 \).
2. The line is represented by \( y = x \).
3. The density function is given by \( \delta(x) = 12x \).
4. The region of integration is defined by the intersection points of \( y = x^2 \) and \( y = x \). Calculating these intersection points:
   
   \[
   x^2 = x \implies x(x - 1) = 0 \implies x = 0 \text{ or } x = 1
   \]
