Answer:
-10x-15
Explanation:
It's 10x-15, because you just need to simplify it.
It is the same thing as (5 x (-2x)) - (5 x 3), if you use the distributive property.
that is the same as -10x-15
So first we start off with 5(-2x-3)
Next, we distribute the 5 to the -2x to get -10x.
Next, we distribute the 5 to the -3 to get -15.
Therefore,
-10x-15 is correct
