Determine any equation where n = 6
Add n to both sides
<em></em><em> ----- This is 1 equation</em>
Multiply both sides by n
<em></em><em> ----- This is another</em>
<em></em>
Add 5n to both sides
<em></em><em> ---- This is another</em>
Subtract 10 from both sides
<em></em><em> --- This is another</em>
<em>You can have as many equations as possible</em>
1. The rectangular prism is a right prism with rectangular bases (check the picture)
2. It has 8 vertices, so we are looking for 3d figures with 4 vertices.
3. A face can have at least 3 vertices, and the 4th must be outside of the plane determined by the first 3 vertices. This makes 4 vertices in total.
4. The 3d figure described in step 3 is a pyramid.
