expand the expression -3(10x-12) what method am i suppose to use is it distributed property if is how do i use it
Yes, you are right. Use distribution and multiply each number in the parenthesis aka the "10x" and "-12" by -3.
So it would be
10x(times -3) - 12(times -3)
-30x - -36
-30x + 36
Thats your answer. Hope this helps!

Yes, Thank you Serena.
Yes, the method you need to use in this case is the distributive property. The distributive property states that when you have a number or expression outside of parentheses multiplied by a sum or difference inside the parentheses, you can distribute the multiplication to each term inside the parentheses.
To expand the expression -3(10x - 12) using the distributive property, you will multiply -3 by each term inside the parentheses, and then combine like terms, if any.
Let's break it down step by step:
1) Multiply -3 by 10x:
-3 * 10x = -30x
2) Multiply -3 by -12:
-3 * -12 = 36
So, expanding the expression -3(10x - 12) using the distributive property, we get:
-3(10x - 12) = -30x + 36
