Answer:

D= 49/8

Step-by-step explanation:

Cross-multiply.

(2d-5)/2 = (5d+2)/9

(2d−5)*(9)=(5d+2)*(2)

18d−45=10d+4

Subtract 10d from both sides.

18d−45−10d=10d+4−10d

8d−45=4

Add 45 to both sides.

8d−45+45=4+45

8d=49

Divide both sides by 8.

d= 49/8

So the answer is 49/8

I hope it's right!

Explain the difference between solids that are polyhedra and solids that are not polyhedra.

zvonat [6]

Answer:

There are no gaps between the edges or vertices in a polyhedron. Examples of polyhedrons include a cube, prism, or pyramid. Non-polyhedrons are cones, spheres, and cylinders because they have sides that are not polygons.
