1) (2 points) Imagine a 21-gonal prism. How many total faces does this prism have? Provide a clear
and detailed justification for your answer, using appropriate vocabulary, that does not rely on a
formula.
Answer: There are 23 faces total.
Explanation:
This is because there are 21 lateral faces, each of which are a rectangle. Then there are the 2 base faces which are each 21-gons. A 21-gon is a 21 sided polygon. So we have 21+2 = 23 faces total.

Answer:
y(5 + 8)
Step-by-step explanation:
I think what this problem wants us to do is take y out of this expression. 5y divided by y is 5 and 8y divided by y is 8, so we would get that this expression is y(5 + 8).
If you wanted to simplify, you would get y(13), which is 13y.
Solve for g in terms of h
6g - 3+ h = 5g - 4h + 13
The answer is g= -5h + 16
Answer:
g = −5h+16
h = −[tex]\frac{g}{5}[/tex]+[tex]\frac{16}{5}[/tex]
Solve for the variable indicated
-4x-8y=36 solve for x
Answer:
x = -2y - 9
Step-by-step explanation:
First isolate the variable by putting the x on a side by itself.
-4x=36+8y (8y becomes positive when it changes sides)
Then divide the entire equation by -4 to make the x stand alone.
x = -9 -2y
Some teachers prefer the variables at the beginning of the equations so it could also read
x = -2y - 9
Hello there!
Question:-
[tex]-4x-8y=36[/tex]
We need to find the value of x.
Solution:-
[tex]\sf \longmapsto-4x-8y=36[/tex]
Firstly, Add 8y to both sides :-
[tex]\sf \longmapsto \: - 4x - 8y+8y=36+8y[/tex]
On Simplification:-
As (-) and (+) equals to (-),It Will be 8y-8y.Answer would be 0.
[tex]\sf \longmapsto \: - 4x - 0 = 36 + 8y[/tex]
[tex]\sf \longmapsto \: - 4x = 8y + 36[/tex]
Then, Divide both sides by -4:-
[tex]\sf \longmapsto \: \dfrac{4x}{ - 4} = \dfrac{8y + 36}{ - 4} [/tex]
On Simplification:-
[tex]\sf \longmapsto \: x = - 2y - 9[/tex]
______________________________________
Henceforth the value of x is :-
[tex] \boxed{\tt \: x = - 2y - 9}[/tex]

hi im 7th grade and i feel like people think i smell when i do everything to not smell. i wake up take a shower with soap aplly deoderant and brush teeth. any tips
Answer:
Step-by-step explanation:
This might be a hygiene problem. What causes the unpleasant smell is the bacteria that build up on your sweaty skin and react with sweat and oils to grow and multiply when sweat reacts with bacteria on the skin. These bacteria break down proteins and fatty acids, causing body odor in the process. If deodorant isn’t good enough , I recommend perfume, the perfume smell lasts longer than deodorant I would think. But shower everyday, full clean down, but if ur hygiene is ok, I recommend going to the doctor for a checkup. Hopefully your problem will be resolved. Also use lotion.

if the price of aluminum cans is 32 cents per pound and it takes 32 cans to make 1 pound how many cans do I need to make $100?
Answer:
1,000 cans
Step-by-step explanation:
Since there are 32 cans per pound and each pound is 32 cents. You divide 32/32 which tells you each can is 1 cent. So 100 dollars divided by 1 cent is 1,000 cents or 1,000 cans since each can is 1 cent.
Answer:
1000 can

The angles of a quadrilateral are in the ratio 2:4:5:6 what is the difference between the largest angle and the smallest angle
Answer:
85
Step-by-step explanation:
From the question given above, the following data were obtained:
Ratios of the angle => 2 : 4 : 5 : 6
Difference between the largest angle and the smallest angle =?
Next, we shall determine the various angles in the quadrilateral. This can be obtained as follow:
Ratios of the angle => 2 : 4 : 5 : 6
Total ratio = 2 + 4 + 5 + 6
Total ratio = 17
Angle in a quadrilateral = 360
For ratio 2:
Angle = 2/17 × 360 ≈ 42
For ratio 4:
Angle = 4/17 × 360 ≈ 85
For ratio 5:
Angle = 5/17 × 360 ≈ 106
For ratio 6:
Angle = 6/17 × 360 ≈ 127
SUMMARY:
The angles are => 42°, 85°, 106° and 127°
Finally, we shall determine the difference between largest angle and the smallest angle. This can be obtained as follow:
Smallest angle = 42°
Largest angle = 127°
Difference between the largest angle and the smallest angle =?
Difference = Largest – Smallest
Difference = 127 – 42
Difference = 85
Thus, the difference between the largest angle and the smallest angle is 85.
