  1. What is the value of x in the equation 3x + 12 = 33?

    Answer: 7

    Subtracting 12 from both sides gives 3x = 21, so x = 7.

  2. A rectangle has a length of 14 cm and a width of 6 cm. What is its area?

    Answer: 84 cm²

    Area of a rectangle = length × width = 14 × 6 = 84 cm².

  3. Which of the following is equivalent to 2/5 as a percentage?

    Answer: 40%

    2 ÷ 5 = 0.40, which equals 40%.

  4. If f(x) = 2x² - 3, what is f(4)?

    Answer: 29

    f(4) = 2(4²) - 3 = 2(16) - 3 = 32 - 3 = 29.

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

    Answer: 2

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

  6. A store sells a jacket originally priced at $120 at a 25% discount. What is the sale price?

    Answer: $90

    25% of $120 = $30, so the sale price is $120 - $30 = $90.
