  1. What is the least common multiple (LCM) of 6 and 8?

    Answer: 24

    Multiples of 6: 6,12,18,24; multiples of 8: 8,16,24 — LCM = 24.

  2. What is the slope of the line passing through (2, 3) and (6, 11)?

    Answer: 2

    Slope = (11 − 3) / (6 − 2) = 8 / 4 = 2.

  3. Simplify: √144

    Answer: 12

    12 × 12 = 144, so √144 = 12.

  4. If a cylinder has radius 3 and height 5, what is its volume? (Use π ≈ 3.14)

    Answer: 141.3

    V = πr²h = 3.14 × 9 × 5 = 141.3.

  5. Factor the expression: x² − 9

    Answer: (x − 3)(x + 3)

    x² − 9 is a difference of squares: (x − 3)(x + 3).

  6. What is the median of the data set: 5, 8, 3, 7, 1?

    Answer: 5

    Sorted: 1, 3, 5, 7, 8 — the middle value is 5.

  7. Which inequality is equivalent to −3x < 12?

    Answer: x > −4

    Dividing both sides by −3 flips the inequality: x > −4.
