Answer:

x=-24 & x=4.

Step-by-step explanation:

-5/6x=20

x=20/(-5/6)

x=(20/1)(-6/5)=-120/5=-24

-------------------------------------

2/3(x-7)=-2

2/3x-14/3=-2

2/3x=-2+14/3

2/3x=-6/3+14/3

2/3x=8/3

x=(8/3)/(2/3)

x=(8/3)(3/2)=8/2=4

Can 12(x^3+y^2)+6(y^2+1) be the factored form of 12x^3+18y^2+6?
Misha Larkins [42]

Answer:

YES

Step-by-step explanation:

So how you can figure this out is you do the Distributive Property.

So it will be 12x^3+12y^2+6y^2+6.

The next thing you have to do is add together the ones that are similar which is 12y^2+6y^2 to get 18y^2.

Your answer is 12x^3+18y^2+6. So YES it can be factored into that form.
