6: Yes

7: Yes

8: No

9: Point M

10: Point N

11: Point M

12: Line NM

Step-by-step explanation:

6: Any 3 points will ALWAYS be coplanar

7: Any 2 points will ALWAYS be collinear

8: They cannot be drawn on 1 straight line

9: They both have point M in their line segments

10: They both have point N in their line segments

11: Line segment LM passes through plane K at Point M.

12: The entire line of MN in plane NMR intersects with Plane K.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
