To multiply (−7)(2)(−2), you can simply multiply the numbers together.
−7 × 2 = −14
Then, −14 × −2 = 28.
Therefore, the correct answer is option 3, 28.
To determine the sign of the product (356,864)(−194,758) without multiplying, you can use the property of multiplying a positive number with a negative number.
Since one of the numbers is negative (−194,758), and multiplying any positive number with a negative number gives a negative result, the sign of the product will be negative.
Hence, the correct answer is option 2, "The sign of the product is negative because a positive multiplied by a negative is a negative."
