Questions and Answers
  • 1. 

    1) p² + p² + p²

    • A.

      3p2

    • B.

      P6

    • C.

      3p

    • D.

      2p3

    Correct Answer
    A. 3p2
    Explanation
    The expression p² + p² + p² can be simplified by combining like terms. Since all three terms have the same base (p) and exponent (2), we can add the coefficients together to get 3p². Therefore, the correct answer is 3p².

  • 2. 

    2) 5(2d + 2e)

    • A.

      7d+ 7e

    • B.

      10d + 10e

    • C.

      15d+ 15e

    • D.

      7de

    Correct Answer
    B. 10d + 10e
    Explanation
    The given expression is 5(2d + 2e), which can be simplified by distributing the 5 to both terms inside the parentheses. This results in 10d + 10e, which is the same as the correct answer.

    Rate this question:

  • 3. 

    3) (2³)4

    • A.

      27

    • B.

      26

    • C.

      212

    • D.

      28

    Correct Answer
    C. 212
    Explanation
    The given expression (2^3)^4 can be simplified by raising 2 to the power of 3, which equals 8. Then, 8 is raised to the power of 4, resulting in 8^4 = 2^12 = 4096. Therefore, the correct answer is 212.

    Rate this question:

  • 4. 

    4) 7x + 4 when x= 6

    • A.

      46

    • B.

      56

    • C.

      26

    • D.

      35

    • E.

      Option 5

    Correct Answer
    A. 46
    Explanation
    When we substitute x = 6 into the expression 7x + 4, we get 7(6) + 4 = 42 + 4 = 46. Therefore, the correct answer is 46.

    Rate this question:

  • 5. 

    5)  y + 3z when y=5 & z=6

    • A.

      28

    • B.

      32

    • C.

      23

    • D.

      28

    Correct Answer
    C. 23
    Explanation
    The correct answer is 23 because when we substitute y=5 and z=6 into the expression y + 3z, we get 5 + 3(6) which simplifies to 5 + 18 = 23.

    Rate this question:

  • 6. 

    6) 14 decreased from a number p

    • A.

      P-14

    • B.

      14-p

    • C.

      P14

    • D.

      14

    Correct Answer
    A. P-14
    Explanation
    The expression "p-14" represents the phrase "14 decreased from a number p". This means that we are subtracting 14 from the number p.

    Rate this question:

  • 7. 

    7) Product of 9 and a number r

    • A.

      9+r

    • B.

      9r

    • C.

      R9

    • D.

      None

    Correct Answer
    B. 9r
    Explanation
    The expression "Product of 9 and a number r" can be written as 9r. This is because when we multiply 9 by any number r, we get the product 9r. Therefore, the correct answer is 9r.

    Rate this question:

  • 8. 

    8) 9x + 24y

    • A.

      3(3x+8y)

    • B.

      33xy

    • C.

      8( 3x+ y)

    • D.

      8( 3x +y)

    Correct Answer
    A. 3(3x+8y)
    Explanation
    The given expression is 9x + 24y. The correct answer, 3(3x+8y), is obtained by factoring out the greatest common factor (GCF) from the terms 9x and 24y. The GCF of 9x and 24y is 3, so we divide both terms by 3 to get 3x and 8y. Therefore, the expression can be simplified as 3(3x+8y), which is the correct answer.

    Rate this question:

  • 9. 

    9)Bob is now d years old. Write an expression for his age in 6 years time.

    • A.

      6d

    • B.

      D + 6

    • C.

      D6

    • D.

      None

    Correct Answer
    B. D + 6
    Explanation
    The expression "d + 6" represents Bob's age in 6 years time. Adding 6 to his current age (d) gives us the age he will be after 6 years.

    Rate this question:

  • 10. 

    10)  4a + 9b – 3a – 5b

    • A.

      A + 4b

      A+ 6b

    • D.

      4a + 4b

    Correct Answer
    A. A + 4b
    Explanation
    The given expression is a combination of like terms. By combining the terms with 'a' and 'b', we can simplify the expression to a + 4b.
