☐ shen finished reading his book in 4 days. each day, he read x pages. his book has 28 pages.
☐ a book is x pages long. shen read 4 pages. he has 28 pages remaining.
☐ a book has two parts. one part is x pages long. the other part is 4 pages long. the book has 28 pages.
☐ none of the above

Explanation:

Step1: Analyze the equation \(4x = 28\)

The equation represents the total number of pages (\(28\)) being equal to the number of days (\(x\)) multiplied by the number of pages read per day (\(4\)).

Step2: Evaluate each option

• Option 1: "Shen finished reading his book in \(x\) days. Each day, he read \(4\) pages. His book has \(28\) pages." This matches the equation \(4x = 28\) (total pages = days × pages per day).
• Option 2: "Shen finished reading his book in \(4\) days. Each day, he read \(x\) pages. His book has \(28\) pages." This would be \(4x = 28\) as well? Wait, no, the equation here would be \(4\times x = 28\) but the description is days = 4, pages per day = \(x\), so total pages \(4x = 28\) – but wait, the first option's description is days = \(x\), pages per day = 4, total pages \(4x = 28\). Wait, actually both? No, wait the first option's description is days = \(x\), pages per day = 4, so total pages \(4x = 28\). The second option is days = 4, pages per day = \(x\), so total pages \(4x = 28\) – but the question is which option matches \(4x = 28\). Wait, the first option: "Shen finished reading his book in \(x\) days. Each day, he read \(4\) pages. His book has \(28\) pages." So total pages = days × pages per day → \(4x = 28\). That's correct.
• Option 3: "A book is \(x\) pages long. Shen read \(4\) pages. He has \(28\) pages remaining." This would be \(x - 4 = 28\), not \(4x = 28\).
• Option 4: "A book has two parts. One part is \(x\) pages long. The other part is \(4\) pages long. The book has \(28\) pages." This would be \(x + 4 = 28\), not \(4x = 28\).
• Option 5: "None of the above" – incorrect as Option 1 matches.

Answer:

The correct option is: Shen finished reading his book in \(x\) days. Each day, he read \(4\) pages. His book has \(28\) pages.
