  1. What is the square root of 144?

    Answer: 12

    The square root of 144 is 12 because 12 x 12 = 144.

  2. Convert 3/8 to a decimal.

    Answer: 0.375

    Dividing 3 by 8: 3 / 8 = 0.375.

  3. If a rectangle has a perimeter of 30 inches and a width of 5 inches, what is its length?

    Answer: 10 inches

    Perimeter = 2(length + width). So 30 = 2(L + 5), meaning L + 5 = 15, and L = 10 inches.

  4. What is the mean (average) of the numbers 14, 18, 22, and 26?

    Answer: 20

    Mean = sum / count = (14 + 18 + 22 + 26) / 4 = 80 / 4 = 20.

  5. Simplify the expression: 4(2x + 3) - 2x

    Answer: 6x + 12

    Distribute: 4(2x) + 4(3) - 2x = 8x + 12 - 2x = 6x + 12.

  6. A circle has a diameter of 14 inches. What is its approximate circumference? (Use pi = 3.14)

    Answer: 43.96 inches

    Circumference = pi x diameter = 3.14 x 14 = 43.96 inches.
