Answer:
The answer should be -5.
Step-by-step explanation:
Remember that if there are two negative signs next to each other then it will turn into a positive sign, in which you get the equation -9 + 4. Your answer should be -5 when you add 4 from -9.
Step 1: You can distribute it by multiplying 6 by 2x and -12, so you get 12x-72= 24
Step 2: Now you can solve it by adding 72 on both sides, so we get 12x= 96, then you can divide 12 on both sides, so we get x=8.

Answer:
Polynomials of degree 8 have exactly 8 roots
Step-by-step explanation:
The Fundamental Theorem of Algebra states that every polynomial of degree n
with
has exactly n roots.
But the roots may be complex numbers.
In your case n=8, so polynomials of degree 8 have exactly 8 roots.
The roots need not be different.
For example, for the polynomial
x=2 is root twice.
An appropriate order for drawing a hexagon is ...
- Use the circle's radius to set the width of the compass.
- Draw a circle using the compass.
- Add a point on the circle.
- Place the point of the compass on the point most recently drawn on the circle.
- Create an arc with the compass that intersects the circle.
- Mark the intersection with a point.
- Repeat the previous step 4 times. [meaning steps 4–6]
- Connect consecutive points with the straightedge.

<em>Comment on this construction</em>
A lot of math is much more understandable if you have real-life experience with physical objects. In geometry, there is really no substitute for actually doing these steps using a compass and straightedge.
One of the things you learn by doing is that you need to be very precise when you're following the process. Otherwise, your hexagon comes out somewhat irregular.
You also find there are other methods (perhaps more accurate and requiring less work), involving symmetry and the center of the circle.
