Which of the following is an integer? Choices: (A)5.237 (B)–9 (C)sqrt 5 (D)sqrt 10

Definition of an Integer: Understand the definition of an integer. An integer is a whole number that can be positive, negative, or zero, but it cannot be a fraction or contain decimal points.Evaluate Choices: Evaluate each choice to determine if it is an integer. (A) 5.237 is a decimal number, not an integer.Choice (B): Evaluate choice (B). (B) –9 is a negative number, but it is a whole number without a fractional or decimal part, so it is an integer.Choice (C): Evaluate choice (C). (C) sqrt(5) is the square root of 5. Since 5 is not a perfect square, its square root is not an integer.Choice (D): Evaluate choice (D). (D) sqrt(10) is the square root of 10. Since 10 is not a perfect square, its square root is not an integer.Identify Integer: Determine which choice is an integer. From the evaluations, only choice (B) –9 is an integer.

Definition of an Integer: Understand the definition of an integer. An integer is a whole number that can be positive, negative, or zero, but it cannot be a fraction or contain decimal points.
Evaluate Choices: Evaluate each choice to determine if it is an integer. $\newline$ (A) $5.237$ is a decimal number, not an integer.
Choice (B): Evaluate choice (B). $\newline$ (B) $–9$ is a negative number, but it is a whole number without a fractional or decimal part, so it is an integer.
Choice (C): Evaluate choice (C). $\newline$ (C) $\sqrt{5}$ is the square root of $5$ . Since $5$ is not a perfect square, its square root is not an integer.
Choice (D): Evaluate choice (D). $\newline$ (D) $\sqrt{10}$ is the square root of $10$ . Since $10$ is not a perfect square, its square root is not an integer.
Identify Integer: Determine which choice is an integer. $\newline$ From the evaluations, only choice (B) $–9$ is an integer.
