-14i is the answer to the equation
Answer: C. The equations have the same solution because the second equation can be obtained by adding 6 to both sides of the first equation.
Step-by-step explanation:
You know that the first equation is:

And the second equation is:

According to the Addition property of equality:
If
; then 
Then, you can add 6 to both sides of the first equation to keep it balanced. Then, you get:


Therefore, you can observe that the second equation can be obtained by adding 6 to both sides of the first equation, therefore, the equations have the same solution.
If you want to verify this, you can solve for "x" from both equations:
- First equation:

- Second equation:

Answer: 55 cubic units
Step-by-step explanation:
Answer:
7.66
Step-by-step explanation:
Just open the parenthesis.
4x-4+4x+4x-4=84
Now simplify and solve
12x-8=84
12x=92
x= 7.66
