Answer:
v = -5, t = -13. , d = -12
Step-by-step explanation:
29) 3v - 9v = 30
Simplifying gives us -6v = 30. Then dividing both sides by -6 reaches our answer of v = -5. 
30)12t - 8t = -52
Simplifying gives us 4t = -52. We can divide both sides by 4 to reach a conclusion that t = -13. 
31) -8d - 5d + 7d = 72 
Simplifying gives us -6d = 72. We can then divide both sides by -6. In doing so, we can achieve our answer that d = -12.

Horizontal cross sections are the same shape: they are all squares if the pyramid is square or rectangles if the pyramid is a rectangle pyramid.
Vertical cross sections are different shape: At the pyramid top they are triangles, at other places they have four sides.
Horizontal cross sections are different size: the more we go to the top of the pyramind, the smaller they get.
Vertical cross sections are different size: the closer we get to the edges, the smaller they become.
