Question

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

Answer 1

Answer:

B

Step-by-step explanation:

The distributive property tells us:

$a(b+c+d)=ab+ac+ad$

So we multiply each term inside the parenthesis with whatever is outside the parenthesis.

The problem given is  $-5x^3(3x^2+3x-1)$

So we multiply $-5x^3$ with each of the terms inside the parenthesis (remembering to take the signs as well). Thus we have:

$-5x^3(3x^2+3x-1)\\=-5x^3*3x^2-5x^3*3x-5x^3*-1\\=-5x^3*3x^2-5x^3*3x+5x^3*1$

Hence answer choice B is right.
