Answer:
Step-by-step explanation:
Just use the distributive property: a(x+y) = ax + ay
1. Factor out the x^1/3.
X^1/3(x^1/3 +2)=0
That means either x^1/3 equals 0 or x^1/3+2 equals 0.
For x^1/3=0, x=0
For x^1/3+2=0
X^1/3=-2
X equals -8
Therefore, x can be 0 or -8
Answer:
d= -6
Step-by-step explanation:
56 = -8d + 8
1) You want to get d by itself. Subtract 8 from both sides.
56 = -8d + 8
- 8 - 8
<em>(8 - 8 = 0, and 56 - 8 is 48.)</em>
48 = -8d
2) Then, you divide my -8 on both sides.
(<em>48 / -8 is -6, and -8d / -8 is just d.)</em>
-6 = d
So, d = -6
