To determine which expression is equivalent to \(5(6x + 3y)\), apply the distributive property by multiplying 5 by each term inside the parentheses:
- \(5 \times 6x = 30x\)
- \(5 \times 3y = 15y\).

Combining these results gives \(30x + 15y\).

**Analysis of options**:
- **A. 11x + 3y**: Incorrect, as neither term is correctly multiplied by 5.
- **B. 11x + 8y**: Incorrect, coefficients do not match the distributive result.
- **C. 30x + 3y**: Partially correct for the \(x\)-term, but the \(y\)-term is not multiplied by 5.
- **D. 30x + 15y**: Correct, both terms are properly distributed.

To find the equivalent expression, we need to distribute the 5 to both terms inside the parentheses:

5(6x + 3y) = 5(6x) + 5(3y)
= 30x + 15y

So, the correct answer is:

D. 30x + 15y

Explanation:
To find an expression equivalent to 5(6x + 3y), we need to apply the distributive property of multiplication over addition.
This property states that for any numbers a, b, and c, a(b + c) = ab + ac.
Using this property, we can expand 5(6x + 3y) as follows:
5(6x + 3y) = 5 * 6x + 5 * 3y
= 30x + 15y
Therefore, the expression equivalent to 5(6x + 3y) is 30x + 15y, which corresponds to option D.

Explanation: To find the equivalent expression, distribute the 5 through the parentheses:

5(6x + 3y) = 5 * 6x + 5 * 3y = 30x + 15y

So, the correct answer is D. 30x + 15y.

deepseekv3 To solve the problem, we need to distribute the multiplication over the addition inside the parentheses. Here's the step-by-step solution:

1. Start with the original expression:
\[
5(6x + 3y)
\]

2. Distribute the 5 to both terms inside the parentheses:
\[
5 \cdot 6x + 5 \cdot 3y
\]

3. Perform the multiplication:
\[
30x + 15y
\]

4. Compare the result with the given options:
- A. \(11x + 3y\)
- B. \(11x + 8y\)
- C. \(30x + 3y\)
- D. \(30x + 15y\)

The expression \(30x + 15y\) matches option D.
