### Polynomial Addition Problem

Consider the following polynomial expression:

\[ (10x - 3 + 7x^2) + (x^2 - 2x + 17) \]

Which of the following options correctly represents the simplified form of the given polynomial expression?

**Options:**

A) \( 8x^2 + 9x + 10 \)

B) \( 11x^2 + 8 + 10x \)

C) \( 8x^2 + 8x + 15 \)

D) \( 10x^2 + 24x - 3 \)

### Steps to Solve:

1. **Arrange the Polynomial Terms by Degree:**
   - Combine like terms (terms with the same power of \( x \)).

2. **Combine Like Terms:**
   - For \( x^2 \) terms: \( 7x^2 + x^2 = 8x^2 \)
   - For \( x \) terms: \( 10x - 2x = 8x \)
   - For constant terms: \( -3 + 17 = 14 \)

3. **Simplify the Expression:**
   - The simplified expression should be: \( 8x^2 + 8x + 14 \)

Based on the given options, the closest match to the simplified polynomial expression \( 8x^2 + 8x + 14 \) is not explicitly listed. Therefore, none of the provided options A, B, C, or D is correct.

**Note:** Ensure to review and verify mathematical operations when solving polynomial expressions.
