Answer:
Length of side a = 4.30 miles
Incomplete question:
The area of the regular polygon is 48 mi2. What is the length of side a? miles
Step-by-step explanation:
The number of sides of sides of the polygon is not given, so we will assume the polygon is an hexagon as shown in the attached image;
Given;
Area = 48 mi^2
Area of an hexagon using side a can be written as;
A = (3/2)√3×a^2
Making a the subject of formula
a = √(2/3√3 ×A)
Substituting the values
a = √(2/3√3 ×48)
a = √(32/√3)
a = 4.30 miles
To find the Length of Polygon Sides ('a') of a square polygon with an area of 48 mi², we apply the formula a = √Area. This gives a = √48 miles. This formula applies specifically to squares.
Given the area of the polygon is 48 square miles, to find the length of a side, we would first need to know the type of polygon.
For instance, if it's a square, the area is calculated by squaring one of its sides (Area = side²).
Here, to find the side length ('a'), we take the square root of the area. So, a = √Area.
Applying this to the given area, a = √48 miles.
However, please note that this formula is for a square.
Other polygons have different formulas for calculating such dimensions.

Hey there!!
( a ) 1 + 3/x²-1 = 2/x-1
x²-1+3/x²-1 = 2/x-1
x²+2/x²-1 = 2/x-1
Note : we can write x²-1 as (x-1)(x+1)
I wrote this with the identity a²-b² = (a+b)(a-b)
x²+2/(x-1)(x+1) = 2/x-1
Multiplying (x-1)(x+1) on both sides
x²+2 = 2(x-1)(x+1) / (x-1)
x²+2 = 2(x+1)
x²+2 = 2x+2
x²-2x = 0
x(x-2)=0
x=0
x-2=0
x=2
x = 0 and 2
( b ) ( √x+3 ) - 1 = x
√x+3 = x+1
x+3 = ( x+1)²
x+3 = x²+2x+1
x+3-x²-2x-1=0
-x+2-x²=0
-x²-x+2=0
x = -b plus or minus √b2 -4ac / 2a
x = -1 plus or minus √ 1 + 8 / 2
-1 plus or minus √9 / 2
-1 plus or minus 3/2
-1 +3 / 2
x = 1
-1 - 3 / 2
-4/2
x = -2
negative cannot be a value
Hence, the answer is
x = 1
