The product of the square of \( x \) and seven is \( 7x^2 \). The simplified value of the expression \( \frac{10}{2+3} + \frac{6+3}{3} \) is **5**.
Solución
Certainly! Let's address both parts of your question step by step.
---
### 1. **The Product of the Square of \( x \) and Seven**
**Expression:**
\[ 7 \times x^2 \]
**Simplified Form:**
\[ 7x^2 \]
**Explanation:**
- "The square of \( x \)" is \( x^2 \).
- The product of \( x^2 \) and seven is simply \( 7x^2 \).
---
### 2. **Simplify Using Order of Operations**
**Expression:**
\[ \frac{10}{2+3} + \frac{6+3}{3} \]
**Step-by-Step Simplification:**
1. **Evaluate Parentheses:**
- \( 2 + 3 = 5 \)
- \( 6 + 3 = 9 \)
So, the expression becomes:
\[ \frac{10}{5} + \frac{9}{3} \]
2. **Perform Division:**
- \( \frac{10}{5} = 2 \)
- \( \frac{9}{3} = 3 \)
Now, the expression is:
\[ 2 + 3 \]
3. **Add the Results:**
- \( 2 + 3 = 5 \)
**Final Simplified Result:**
\[ 5 \]
---
**Summary:**
- The product of the square of \( x \) and seven is \( 7x^2 \).
- The simplified value of the expression \( \frac{10}{2+3} + \frac{6+3}{3} \) is **5**.

To simplify the expression, we will follow the order of operations (PEMDAS/BODMAS). Start with the denominators: 1. \( 2 + 3 = 5 \) 2. \( 6 + 3 = 9 \) 3. Now, substitute these values into the expression: \[ \frac{10}{5} + \frac{9}{3} \] Next, perform the divisions: 1. \( \frac{10}{5} = 2 \) 2. \( \frac{9}{3} = 3 \) Finally, add the results together: \[ 2 + 3 = 5 \] Thus, the simplified expression is \( 5 \).
