Question

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

Answer 1

Answer:

option-B

Step-by-step 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
