Question

What is the sign of the product (8)(−23)(−21)(−29)?

Options:
A) Positive, because the products (8)(−23) and (−21)(−29) are negative, and the product of two negative numbers is positive

B) Positive, because the products (8)(−23) and (−21)(−29) are positive, and the product of two positive numbers is positive

C) Negative, because the product (8)(−23) is positive and the product (−21)(−29) is negative, and the product of a positive number and a negative number is negative

D) Negative, because the product (8)(−23) is negative and the product (−21)( −29) is positive, and the product of a negative number and a positive number is a negative number

Answer 1

D

Explanation:

If there are an even number of negative signs, the product will be even.

If there is an odd number of negative signs, the product will be odd.

In this case, there are 3 negative signs, so the product will be negative.

It's D.

*Note: it's not C because the product of (8) and (-23) is negative, not positive because there is only one negative sign, not two.

Answer 2

D) Negative, because the product (8)(−23) is negative and the product (−21)( −29) is positive, and the product of a negative number and a positive number is a negative number
