Questions and Answers
  • 1. 

    Write the expression for a) 32 plus a number n b) 58 less than a number n

    • A.

      32+n, n-58

    • B.

      32-n, 58+n

    • C.

      32-58+n

    • D.

      32-n+58

    Correct Answer
    A. 32+n, n-58

  • 2. 

    The coefficient of x² in – 5x²y is

    • A.

      Y

    • B.

      -5

    • C.

      -5y

    • D.

      5

    Correct Answer
    B. -5
    Explanation
    The coefficient of x² in -5x²y is -5y. This is because the coefficient of x² is the number that multiplies x², and in this case, it is -5. 

    Rate this question:

  • 3. 

    The value of 3x² – 5x + 3, if x=1 is

    • A.

      1

    • B.

      -1

    • C.

      0

    • D.

      2

    Correct Answer
    A. 1
    Explanation
    When x=1, we substitute the value of x into the expression 3x² - 5x + 3. This gives us 3(1)² - 5(1) + 3, which simplifies to 3(1) - 5 + 3. Further simplifying, we get 3 - 5 + 3, which equals 1. Therefore, the value of 3x² - 5x + 3 when x=1 is 1.

    Rate this question:

  • 4. 

    Solve the equation: –z² + 22z² – 5z – 11z² + 5z

    • A.

      10 z2

    • B.

      Z

    • C.

      -10 z2

    • D.

      Z

    Correct Answer
    A. 10 z2
    Explanation
    The equation is simplified by combining like terms. By combining the terms -z^2, 22z^2, -11z^2, and 10z^2, we get 10z^2. Therefore, the correct answer is 10z^2.

    Rate this question:

  • 5. 

    The expression 4p²q – 4pq² + 1 is a

    • A.

      Binomial

    • B.

      Trinomial

    • C.

      Monomial

    • D.

      None of the above

    Correct Answer
    B. Trinomial
    Explanation
    The given expression has three terms: 4p²q, -4pq², and 1. Therefore, it is a trinomial.

    Rate this question:

  • 6. 

    I= PRT so what does R=

    • A.

      I/PT

    • B.

      PT/I

    • C.

      T/PI

    • D.

      P/TI

    Correct Answer
    A. I/PT
    Explanation
    The formula I = PRT represents the relationship between interest (I), principal (P), rate (R), and time (T). To find the value of R, we need to isolate it on one side of the equation. By dividing both sides of the equation by PT, we get R = I/PT. This means that the rate is equal to the interest divided by the product of the principal and time.

    Rate this question:

  • 7. 

    Which of the following pairs of terms is of unlike terms?

    • A.

      -p²q², 12p²q²

    • B.

      Qp², 13p²q

    • C.

      41,100

    • D.

      – 4x²; – Axy²

    Correct Answer
    D. – 4x²; – Axy²
    Explanation
    The given pair of terms, "-4x^2" and "-Axy^2", is of unlike terms because they have different variables. The first term has a variable "x" raised to the power of 2, while the second term has a variable "xy" raised to the power of 2. Additionally, the coefficient of the second term is a variable "A", whereas the coefficient of the first term is a constant "-4". Therefore, this pair of terms is unlike.

    Rate this question:

  • 8. 

    (5x – y + 8) - (5x + 3y)

    • A.

      4x – 8

    • B.

      4y – 8

    • C.

      8 – 4y

    • D.

      4x + 8

    Correct Answer
    C. 8 – 4y
    Explanation
    The given expression is (5x – y + 8) - (5x + 3y). To simplify this expression, we can remove the parentheses and combine like terms. Distributing the negative sign inside the second set of parentheses, we get 5x - y + 8 - 5x - 3y. Combining like terms, we have -4y + 8. Therefore, the correct answer is 8 – 4y.

    Rate this question:

  • 9. 

    Subtracting -3x² – 1 from 2x + 1

    • A.

      – 3x² + 2x – 2

    • B.

      – 3x² + 2

    • C.

      3x² – 2

    • D.

      3x² + 2x + 2

    Correct Answer
    D. 3x² + 2x + 2
    Explanation
    The given expression is subtracting -3x^2 - 1 from 2x + 1. To subtract the expression, we distribute the negative sign to each term in -3x^2 - 1, which gives us -(-3x^2) - (-1). Simplifying further, we get 3x^2 + 2. Thus, the correct answer is 3x^2 + 2x + 2.

    Rate this question:

  • 10. 

    What is the coefficient of y2 in the expression 3y2 + 4x?

    • A.

      3

    • B.

      4

    • C.

      1

    • D.

      X

    Correct Answer
    A. 3
    Explanation
    The coefficient of y^2 in the expression 3y^2 + 4x is 3. This is because the coefficient is the number that multiplies the variable, which in this case is y^2. The coefficient of y^2 is 3, as it is the number that is directly in front of the variable term.
