    What is (3x+5y)(8x+9y)?

    Explanation
    The given expression is a product of two binomials. To find the product, we use the distributive property. First, we multiply 3x by each term in the second binomial, which gives us 24x^2 and 27xy. Then, we multiply 5y by each term in the second binomial, which gives us 40xy and 45y^2. Combining like terms, we have 24x^2 + 67xy + 45y^2.

    Is this tautology? - ProProfs

    Is this tautology?

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The given question is asking if the statement is a tautology. A tautology is a statement that is always true, regardless of the truth values of its variables. Since the given statement is "False," it cannot be a tautology because it is not always true. Therefore, the correct answer is False.

    What kind of logic is this table showing - ProProfs

    What kind of logic is this table showing

    • Nor

    • Or

    • And

    • Not

    Correct Answer
    A. Or
    Explanation
    The table is showing the logic of the "Or" operation. The "Or" logic returns true if at least one of the inputs is true, and false only if both inputs are false. In this table, the inputs are labeled as "Nor," "Or," "And," and "Not," but the correct answer is "Or," indicating that the table represents the logical operation of "Or."

    `I will take my umbrella only if it is both about to rain and I can find it` This is an example of which type of logic?

    • And

    • Or

    • Not

    • Nor

    Correct Answer
    A. And
    Explanation
    This statement represents the logical operator "And" because it requires both conditions to be true in order for the action to occur. The person will take their umbrella only if two conditions are met: it is about to rain and they can find it. If either of these conditions is not true, they will not take the umbrella.

    "The burglar alarm will go off if either the door or the window or both are opened". This is an example of which type of Logic?

    • Not

    • And

    • Nor

    • Or

    Correct Answer
    A. Or
    Explanation
    The given statement states that the burglar alarm will go off if either the door or the window or both are opened. This is an example of the logical operator "or" because it implies that if any of the conditions (door being opened or window being opened) is true, then the alarm will go off.

    What is (x+y)(3z+5)?

    Correct Answer
    3xz+5x+3yz+5y
    Explanation
    The given expression is a multiplication of two binomials. To find the product, we use the distributive property. We multiply each term of the first binomial (x+y) by each term of the second binomial (3z+5). This results in four terms: 3xz, 5x, 3yz, and 5y. Therefore, the correct answer is 3xz+5x+3yz+5y.

  • 8. 

    What is(x+4)(x-4)? 

    Correct Answer
    x^2-16
    Explanation
    The given expression is a product of two binomials, (x+4) and (x-4). When we multiply these binomials using the FOIL method, we get x^2 - 4x + 4x - 16. The middle terms, -4x and +4x, cancel each other out, leaving us with x^2 - 16.

    What type of logic is this table showing? - ProProfs

    What type of logic is this table showing?

    • Xor

    • Nor

    • And

    • Or

    Correct Answer
    A. Nor
    Explanation
    The table is showing the logic gate known as "Nor." Nor gate is a digital logic gate that produces an output of true (1) only when all of its inputs are false (0). It is the inverse of the "Or" gate, as it gives the opposite output. This means that if any input in the Nor gate is true, the output will be false.

    Give 3 mathematicians in geometry

    Correct Answer
    Euclid,Plato,aristotle
    Explanation
    Euclid, Plato, and Aristotle are all well-known mathematicians who made significant contributions to the field of geometry. Euclid is often referred to as the "Father of Geometry" for his work in developing the foundational principles and theorems of the subject. Plato, a philosopher, also made contributions to geometry through his exploration of the nature of geometric forms and their relationship to reality. Aristotle, another philosopher, further expanded on these ideas and explored the philosophical implications of geometry. Together, these three mathematicians played a crucial role in shaping the study of geometry as we know it today.
