Answer:
   n = 4
Step-by-step explanation:
Put the given values in the equation and solve for n.
   9 = 4n -7
   16 = 4n . . . . . . add 7
   4 = n . . . . . . . . divide by 4
The value of n is 4 so that m(4) = 9.
 
        
             
        
        
        
Answer:
314 in²  (nearest whole number)
Step-by-step explanation:
<u>Radius of a regular polygon</u>: The distance from the <u>center</u> of the polygon to any vertex.  The radius of a hexagon is equal to the length of one side.
Therefore, from inspection of the given diagram:
- radius = 11 in  ⇒  side length = 11 in
To find the area of a regular polygon, we first need to calculate the apothem.   The <u>apothem</u> is the line drawn from the center of the polygon to the midpoint of one of its sides.

where:
- s = length of one side
- n = number of sides
Given:
Substitute the given values into the formula and solve for a:

<u>Area of a Regular Polygon</u>

where:
- n = number of sides
- s = length of one side
- a = apothem
Given:
Substitute the given values into the formula and solve for A:



 
        
             
        
        
        
Marks of Bobbie = x
Then, marks of Georgia 
= 3 times marks of Bobbie
= 3 times m
= 3 × m
= 3m
 
        
             
        
        
        
Answer:
x=2.116
Step-by-step explanation:
 -4x=x-6
 -4x=x-6
4.58-4x-x=-6
-5x=-6-4.58
-5x=-10.58
x=2.116
