Answer 1

To simplify the expression -3(4 + 7), you can use the distributive property of multiplication over addition.

Step-by-step explanation:

To simplify the expression -3(4 + 7), we can use the distributive property of multiplication over addition. This property states that a number multiplied by the sum of two numbers is equal to the product of the number multiplied by each term individually and then added together. In this case, we have:

-3(4 + 7) = -3 * 4 + (-3) * 7

This simplifies to:

-12 + (-21) = -33

Therefore, another way to write -3(4 + 7) is -33. The correct answer is option D: -3.4 + (-3).7.
