### Educational Content on Translating Verbal Phrases into Mathematical Expressions

#### Question:
Which of the following expressions represents the phrase "twice the sum of a number and 5"?

#### Available Answer Choices:
- A) 2x + 5
- B) 2(5) + x
- C) 2(x + 5)
- D) \( (x + 5)^2 \)

#### Explanation:
To translate the phrase "twice the sum of a number and 5," let's break it down:

1. **Identify the sum of a number and 5:**
   - The sum of a number (which we'll call \( x \)) and 5 is expressed mathematically as \( x + 5 \).

2. **Twice the sum:**
   - To take "twice" this sum means to multiply the entire sum by 2.

Therefore, twice the sum of \( x \) and 5 is represented by the expression \( 2(x + 5) \).

#### Correct Answer:
The correct mathematical expression is:
- **C) 2(x + 5)**

This expression correctly represents the phrase as it multiplies the entire sum \( x + 5 \) by 2, indicating "twice the sum of a number and 5".

#### Image Analysis:
The image shows a question on a computer screen with multiple-choice options for selecting the correct mathematical expression based on the provided verbal phrase. Specifically, option C \( 2(x + 5) \) is selected, indicating it as the accurate representation.
