The image provided asks to solve two problems based on the given information \( f(x) = x^3 + 5x \) and \( g(x) = x \). The problems require finding \( f'(7) \cdot g'(7) \) and \( f'(7) \cdot g(7) \).

### Step 1: Find the derivatives of \( f(x) \) and \( g(x) \)
1. **For \( f(x) = x^3 + 5x \):**
   \[
   f'(x) = 3x^2 + 5
   \]

2. **For \( g(x) = x \):**
   \[
   g'(x) = 1
   \]

### Step 2: Evaluate the derivatives and functions at \( x = 7 \)
1. **Evaluate \( f'(7) \):**
   \[
   f'(7) = 3(7)^2 + 5 = 3(49) + 5 = 147 + 5 = 152
   \]

2. **Evaluate \( g'(7) \):**
   \[
   g'(7) = 1
   \]

3. **Evaluate \( g(7) \):**
   \[
   g(7) = 7
   \]

### Step 3: Calculate the required values
1. **For \( f'(7) \cdot g'(7) \):**
   \[
   f'(7) \cdot g'(7) = 152 \cdot 1 = 152
   \]

2. **For \( f'(7) \cdot g(7) \):**
   \[
   f'(7) \cdot g(7) = 152 \cdot 7 = 1064
   \]

### Final Answers:
1. \( f'(7) \cdot g'(7) = 152 \)
2. \( f'(7) \cdot g(7) = 1064 \)
