Let's analyze the question:

The expression given is:
\[
7 + (6 + 8)
\]

### Step 1: Simplify the Expression
1. Simplify the expression inside the parentheses first:
   \[
   6 + 8 = 14
   \]
2. Substitute back to get:
   \[
   7 + 14 = 21
   \]

### Evaluating Each Option
1. **21** – Correct, as \(7 + (6 + 8) = 21\).
2. **336** – Incorrect, as this is not relevant to the addition problem.
3. **(7 ⋅ 6) ⋅ 8** – Incorrect, as this expression involves multiplication, not addition.
4. **(7 + 6) + 8** – Correct, because this uses the associative property of addition, which allows us to regroup terms without changing the result.
5. **Associative property of addition** – Correct, because the problem involves regrouping using this property.

### Correct Answers
The correct options to select are:
- **21**
- **(7 + 6) + 8**
- **Associative property of addition**
