### Distance and Midpoint of Two Points in 3D Space

#### Problem Statement:
Give the distance between the two points (rounded to the nearest hundredth, if needed) and the exact midpoint by filling in the \( x \)-, \( y \)-, and \( z \)-coordinates.

#### Points to Consider:
- Point A: \((3, 2, -4)\)
- Point B: \((6, 8, 2)\)

#### Required Calculations:
1. **Distance** between the two points.
2. **Midpoint** of the line segment joining the two points.

#### Distance Formula in 3D:
\[ d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2 + (z_2 - z_1)^2} \]

#### Midpoint Formula in 3D:
\[ \text{Midpoint} = \left( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2}, \frac{z_1 + z_2}{2} \right) \]

### Solution:

#### Calculate the Distance:

Using the distance formula:
\[ d = \sqrt{(6 - 3)^2 + (8 - 2)^2 + (2 + 4)^2} \]

#### Calculate the Midpoint:

Using the midpoint formula:
\[ \text{Midpoint} = \left( \frac{3 + 6}{2}, \frac{2 + 8}{2}, \frac{-4 + 2}{2} \right) \]

#### Fill in your answers:

- **Distance** = \_\_\_\_ units
- **Midpoint** = ( \_\_\_\_ , \_\_\_\_ , \_\_\_\_ )

Complete the calculations and fill in the blanks to find the correct answers.
