The cuic equation is -1 and 2i
Answer:
The solution is 
Step-by-step explanation:
We need to write everything as a power of 3.
We know that:

So

And

This following property is also important:

To solve, the first step is putting everything with the variable x on one side and everything without the variable x on the other side





This means that:



Answer: 
Step-by-step explanation:
The equation of the line is Slope-intercept form is:

Where "m" is the slope and "b" the y-intercept.
The slopes of perpendicular lines are negative reciprocal.
Then, if the slope of the first line is -3, the slope of the other line must be:

Substitute the point (3,4) into the equation and solve for b:

Then the equation of this line is:

The answer for your exact question is
Answer:
D
Step-by-step explanation:
Because A isn' at all right and B, and C equal the same but D = 36 So the sides are 18 each side.
