  1. What is the area of a triangle with base 10 cm and height 6 cm?

    Answer: 30 cm²

    Area = (1/2) × base × height = 0.5 × 10 × 6 = 30 cm².

  2. Which value of x makes the equation 5x − 10 = 2x + 8 true?

    Answer: x = 6

    3x = 18; x = 6.

  3. A rectangle has a perimeter of 36 cm and a width of 8 cm. What is its length?

    Answer: 10 cm

    Perimeter = 2(l + w); 36 = 2(l + 8); l + 8 = 18; l = 10 cm.

  4. Which table of values represents a linear relationship?

    Answer: x: 1,2,3; y: 3,5,7

    In x: 1,2,3; y: 3,5,7, y increases by 2 for every 1-unit increase in x, showing a constant rate (linear).

  5. Solve: (x/4) + 3 = 7

    Answer: x = 16

    x/4 = 4; x = 16.

  6. The volume of a rectangular box is 120 cm³. If the length is 5 cm and width is 4 cm, what is the height?

    Answer: 6 cm

    Volume = l × w × h; 120 = 5 × 4 × h; h = 120/20 = 6 cm.
