  1. What is the value of 3² + 4²?

    Answer: 25

    3² = 9 and 4² = 16, so 9 + 16 = 25.

  2. A rectangle has a length of 12 cm and a width of 5 cm. What is its area?

    Answer: 60 cm²

    Area of a rectangle = length × width = 12 × 5 = 60 cm².

  3. Simplify: 4x + 3y − 2x + y

    Answer: 2x + 4y

    Combine like terms: (4x − 2x) + (3y + y) = 2x + 4y.

  4. What is 15% of 200?

    Answer: 30

    15% of 200 = (15/100) × 200 = 30.

  5. The mean of five numbers is 8. If four of the numbers are 6, 9, 7, and 10, what is the fifth number?

    Answer: 8

    Sum = 5 × 8 = 40; 40 − (6 + 9 + 7 + 10) = 40 − 32 = 8.

  6. Which of the following is a prime number?

    Answer: 41

    41 has no divisors other than 1 and itself, so it is prime.

  7. Solve for x: 2x − 6 = 10

    Answer: x = 8

    Add 6 to both sides: 2x = 16, then divide by 2: x = 8.
