100 ! brainliest if

write and simplify a polynomial expression for the surface area of each figure.

Step-by-step explanation:

I'm going to make some assumptions here before we start.  The way you have typed this only gives 2 dimensions.  Are we supposed to rotate this around an axis?

1)  That it's 3 dimensional (they ask for surface area).  2D would just say area.  Not surface area.

2)  That r stands for radius

3)  That it's circular (they give a radius).  But radii are not usually negative.  So where is this defined?

Let's make a chart with a few points to try to "see" what we're working with.  

r = x h = x + 9

1               10

2               11

5               14        

0.1             9.1

Things certainly LOOK linear.  This is born out by the equation h = x +9.  H  Could it be a cone?

My best GUESS is that this is a cone.  Or maybe a half of a cone.  But there really is not enough given to be absolutely sure.  Did the teacher give some instructions in class that are not here?

h|  

 |     /

 |    /

 |   /

 |  /

9|/

 |  x = r

This has me intrigued.  If there is more to this, would you please tell me what got left out? hes correct give him brainlist i just did this for him

Yellow shape:

2x + x + 3 + 2x + 1

5x + 4

Blue shape:

w + 3 + w - 1

2w + 2

Orange shape (toddler terms lol):

2y + 2y + 1 + 3y + y + 3

8y + 4

Combine like terms

Always put variables first.

i can tell you jamal now has 3 cookies xd

tommy has 2.

this made me lol.

i think the correct option is the second option.
