Question

Write an equivalent expression by distributing the "-" sign outside the parentheses:

-(6y - 9.6z + 3)

A. -6y - 9.6z + 3
B. -6y + 9.6z - 3
C. 6y - 9.6z - 3
D. 6y + 9.6z + 3

Answer 1

To distribute the '-' sign, multiply each term inside the parentheses by -1, resulting in -6y + 9.6z - 3 (option B).

Step-by-step explanation:

To write an equivalent expression by distributing the "-" sign outside the parentheses for the expression -(6y - 9.6z + 3), you need to multiply each term inside the parentheses by -1. Here is how it works step-by-step:

• Multiply -1 with 6y to get -6y.
• Multiply -1 with -9.6z to get +9.6z (the signs change because multiplying two negatives gives a positive).
• Multiply -1 with +3 to get -3 (a negative times a positive is a negative).

So, the equivalent expression after distributing the minus sign is -6y + 9.6z - 3, which corresponds to option B.
