  1. Simplify: (3x²y)(4xy³)

    Answer: 12x³y⁴

    Multiply coefficients: 3 × 4 = 12; add exponents: x²⁺¹ = x³, y¹⁺³ = y⁴ → 12x³y⁴.

  2. A triangle has angles measuring 35° and 78°. What is the measure of the third angle?

    Answer: 67°

    180° − 35° − 78° = 67°.

  3. What is 15% of 240?

    Answer: 36

    15% × 240 = 0.15 × 240 = 36.

  4. A car travels 180 miles in 3 hours. At the same rate, how far will it travel in 5 hours?

    Answer: 300 miles

    Speed = 180 ÷ 3 = 60 mph; distance in 5 hours = 60 × 5 = 300 miles.

  5. Which expression is equivalent to 4(3x − 2) − 2(x + 5)?

    Answer: 10x − 18

    12x − 8 − 2x − 10 = 10x − 18.

  6. The probability of drawing a red card from a standard 52-card deck is:

    Answer: 1/2

    A standard deck has 26 red cards out of 52, so the probability is 26/52 = 1/2.

  7. Which number is irrational?

    Answer: √50

    √50 cannot be simplified to a whole number or simple fraction; √49=7, √36=6, √25=5 are all rational.
