Chuck says that he can draw a cylinder on his polyhedron poster because it has a pair of base that are congruent.Is chuck correc
Harlamova29_29 [7]

Answer:

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  

Please have a look at the attached photo.  

My answer:

1. Chuck wants to draw three-dimensional figures whose lateral faces are rectangles. He says he can draw prisms and pyramids. Do you agree

No, I do not agree because:

  • The lateral faces of a pyramid are triangles
  • The lateral faces of a prism are rectangles

2. Part B. Chuck says that he can draw a cylinder on his polyhedron poster because it has a pair of bases that are congruent.

No, do not agree because:

A  cylinder has two congruent bases but it is not a  polyhedron while a cylinder has a curved surface when a polyheron has faces that are polygons

Hope it will find you well.

In combining like terms, what do these equations equal?
tester [92]

Answer:

Look below. The answers are bolded!

Step-by-step explanation:

1.   <em>10x + 23</em>

5+6(2x+3)-2x

Distribute first!

5 + 12x + 18 -2x.

Now you can combine like terms.

23 + 10x



2.   <em>18x + 6</em>

3(4x+8) + 3(2x-6)

Distribute first!

12x + 24 + 6x - 18

Now you can combine like terms.

18x + 6



3. <em>-2x + 8</em>

(32-8x)

____ ___

     4

Divide 32 and -8x by 4.


32/4 = 8

-8x/4 = -2x


-2x + 8



4. <em>4x + 3</em>

24x+18

______

    6


Divide 24x and 18 by 6

24x/6 = 4x

18/6 = 3


4x + 3
