Answer:
it has 11 faces 10 sides for the decagon + 1 for the base
It does have one face that is a decagon, which is the base, the rest are triangles
it has 20 edges
Step-by-step explanation:
 
        
                    
             
        
        
        
3(2x-6)-7x+4
3*2x=6x. 3*-6=-18
-7x+6x=-1x. -18+4=-14
-1x/-1=x. -14/-1=14
X=14
        
             
        
        
        
Answer:
1/3(3.14)2^2(24)
Step-by-step explanation:
The volume of a cone is given by the formula;
1/3πr³
Considering the radius is 2 cm and the height is 24 cm (4 times the diameter).
Therefore;
Volume = 1/2(3.14)2²(24)
             This can be used to calculate the volume.
 
        
             
        
        
        
Answer:  
<u>Step-by-step explanation:</u>
y = 8x² - 3            (Restriction: none -  x is All Real Numbers)
The inverse is when you swap the x's and y's and then solve for y
x = 8y² - 3            <em>swapped the x and y</em>
x + 3 = 8y²           <em>added 3 to both sides</em>
 <em>divided both sides by 8</em>
           <em>divided both sides by 8</em>
 <em>square rooted both sides</em>
           <em>square rooted both sides</em>
 <em>simplified</em>
           <em>simplified</em>

           <em>simplified</em>
<u>Restriction:</u> 
The radical <em>(inside the square root sign)</em> cannot be negative
→  2(x + 3) ≥ 0
       x + 3 ≥ 0         <em>divided both sides by 2</em>
       x       ≥ -3         <em>subtracted 3 from both sides</em>
