Answer:

B. triangular pyramid.

Step-by-step explanation:

-Octahedron has eight faces that are equilateral  triangles, six vertices and twelve edges.

-Triangular pyramid has four triangular faces that have congruent isosceles triangles in which one of them is considered the base.

-Right triangular pyramid has a triangle base, three faces and six edges and the line that is located between the centre of the base and the vertex is perpendicular to the base.

-Regular rectangular prism has twelve sides, 8 vertices and six rectangular faces.

According to this, the answer is triangular pyramid.

How do you graph D? PLz explain. HELPPPPPPPPPPPPPPP
yanalaym [24]
See the attached image for the graph. Specifically figure 2 is the graph you want. You can leave the red points on the graph or decide to erase them (leave behind the blue line though). 

To generate each of the red points, you'll plug in various x values to get corresponding y values.

For instance, plug in x = 0 and we get...
y = -|x-6| - 6
y = -|0-6| - 6
y = -|-6| - 6
y = -6 - 6
y = -12
So when x = 0, the y value is -12. The x and y value pair up to get (x,y) = (0,-12)

Another example: plug in x = 2
y = -|x-6| - 6
y = -|2-6| - 6
y = -|-4| - 6
y = -4 - 6
y = -10
So the point (2,-10) is on the graph

The idea is to generate as many points as possible so we get an idea of what this thing looks like. 

Generate enough points, and you'll get what you see in Figure 1 (see attached image)

Then draw a line through all of the points. The more points you use, the more accurate the drawing. Doing that will generate the blue function curve you see in Figure 2 (also attached)
