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

FrozenT [24]

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

For questions 1- 3 find the exact sum or difference.

7nadin3 [17]

D, Because 7/15 + 9/15 is 16/15 + 4/15 =20/15 which equals 1 5/15 which turns into 1 1/3
A, 1/21 + 2/21 = 3/21 and that equals 1/7

C, 3/14+3/12 turns into 3/14+5/14= 10/14 - 8/14= 2/14=1/7
