Answer 2

A, B and C are correct

Explanation:

`(-a)(b)=-ab`

`(-a)(-b)=ab`

`\sf A) \quad 3(-18)(5)=3(-90)=-270`

`\sf B) \quad (-7)(-3)(10)=7 \cdot 3 (10)=21(10)=210`

`\sf C) \quad (4)(-25)(-10)=(4)(25 \cdot 10)=(4)(250)=1000`

`\sf D) \quad (-3)(-5)(8)=(3 \cdot 5)(8)=(15)(8)=120`

`\sf E) \quad (-10)(-10)(-10)=(10 \cdot 10)(-10)=(100)(-10)=-1000`
