Question

Which is an example of using the distributive property to multiply?

Answer 1

option-B

Explanation:

we are given

`-5x^3(3x^2+3x-1)`

we can use distributive property

Distributive property:

`a(x+y+z)=a\cdot x+a\cdot y+a\cdot z`

now, we can apply this formula

and we get

`-5x^3(3x^2+3x-1)=-5x^3\cdot 3x^2-5x^3\cdot 3x-5x^3\cdot -1`

we can see that there are two negative signs in last term

so, we can write as

`-5x^3(3x^2+3x-1)=-5x^3\cdot 3x^2-5x^3\cdot 3x+5x^3\cdot 1`

so,

option-B
