| deepseekr1 | To determine the equivalent expression for 5(4x + 3) − 2x, follow these steps: 1. **Expand the parentheses**: \( 5(4x + 3) = 20x + 15 \). 2. **Subtract 2x**: \( 20x + 15 - 2x \). 3. **Combine like terms**: \( (20x - 2x) + 15 = 18x + 15 \). The simplified expression is **18x + 15**, which matches **Option A**. Answer: A |

| minimax | To solve the expression 5(4x + 3) — 2x, we first distribute the 5 across the terms inside the parentheses and then subtract 2x: 5(4x + 3) — 2x = (5 * 4x) + (5 * 3) — 2x = 20x + 15 — 2x = (20x — 2x) + 15 = 18x + 15 So the equivalent expression is 18x + 15. Answer: A. 18x+15 |

| kimi | To solve this problem, we need to distribute the 5 into the parentheses and then subtract 2x from the result. Step 1: Distribute the 5 into the parentheses: \[ 5(4x + 3) = 5 \cdot 4x + 5 \cdot 3 = 20x + 15 \] Step 2: Subtract 2x from the result: \[ 20x + 15 - 2x = 18x + 15 \] So the expression equivalent to \( 5(4x + 3) - 2x \) is \( 18x + 15 \). Answer: A. 18x+15 |

| wenxinyiyan | B Explanation: We need to expand and simplify the given expression: 5(4x + 3) - 2x = 5 * 4x + 5 * 3 - 2x (Using distributive property) = 20x + 15 - 2x = 18x + 15 (Combining like terms) But, this is not one of the options. Upon closer inspection, we notice that there is a typo in option A, which reads "18x+15" instead of the correct "18x + 15". So, the mathematical expression is equivalent to option B after correction. Note: There seems to be a typo or mistake in the options provided. Based on the calculation, the correct answer should be 18x + 15, which is not directly listed. If we assume option A was meant to be 18x + 15 instead of 18x+15, then A would be the correct answer. But since it's written as 18x+15, we choose the closest matching option, which is B. 18x+3, as it seems to represent the intention of the original (possibly typo'd) answer. In a real test setting, it's important to clarify such ambiguities with the test administrator. |

| zhipu | To find the expression equivalent to \( 5(4x + 3) - 2x \), let's simplify it step by step: 1. Distribute the 5 into the parentheses: \[ 5(4x + 3) = 5 \cdot 4x + 5 \cdot 3 = 20x + 15 \] 2. Subtract \( 2x \) from the result: \[ 20x + 15 - 2x = 18x + 15 \] So, the expression \( 5(4x + 3) - 2x \) simplifies to \( 18x + 15 \). Therefore, the correct answer is: A. 18x+15 |
