Final answer:
To distribute negative one from each of the negative numbers in the expression -3x + 2y - 5z, we change the sign of each term to obtain 3x - 2y + 5z.
Step-by-step explanation:
To distribute negative one from each of the negative numbers, we will change the sign of each term in the expression.
The expression in part B is: -3x + 2y - 5z
When we distribute negative one, we obtain: -(-3x) + (-2y) + (-5z) = 3x - 2y + 5z
