Answer 2

Hi there!


`- 5(3x - 2)`
We can use rainbow technique to get rid of the parenthesis. We need to multiply -5 by 3x and -5 by -2.


`- 5 * 3x - 5 * - 2`
Multiply. Remember that multiplying a negative by a negative gives a positive. When we multiply a negative by a positive, we end up with a negative.


`- 15x + 10`
The 4th answer is correct.
