Let's solve each question one by one:**97. Solve the inequality :**1. Add 7 to both sides: 2. Divide both sides by 3: The correct answer is **D) **.---**98. Find numbers between 20 and 70 that are prime and have a product of digits equal to 6:**- **Prime Numbers between 20 and 70:** 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67- **Numbers with a product of digits equal to 6:** - Consider two-digit numbers where the product of the digits equals 6: - Possible pairs: (1, 6), (2, 3), (3, 2), (6, 1) - Corresponding numbers: 16, 23, 32, 61- **Intersection of Prime Numbers and Product Condition:** - From the list above, only 23 and 61 are prime.Thus, there are **2** numbers that meet both conditions. The correct answer is **A) 2**.---**99. Simplify the expression \(5x^{2} - 4x + 2 - (3x^{2} + 5x - 1)\):**1. Distribute the negative sign: 2. Combine like terms: - - - The simplified form is .The correct answer is **D) **.
