x3+8=0

(x-2) (x2-2x+4)<----- use Quadratic formula

x-2=0 =1+/- 1i sqrt 3

x=2

-For the first step, it's actually (x+2) (x^2-2x+4), not (x-2) (x^2-2x+4).

2 cubed = 2*2*2 =8. 8+8+8= 24

Since 7x + 13x +2x + 8 is an expression (there is no equal sign), there is no answer as to what x equals. However, this expression can be simplified to 22x + 8.

The expression 9+5 is equivalent.

It is: 8+7 = 15

Yes.
