Change it 2.7 * 3 then keep one which is the decimal then multiply 27 * 3 which is 81 we do have the decimal so the answer is 8.1

solniwko [45]
The answer is: 13 units.  
__________________________________________________
Each side of the park is 13 units long.
_______________________________
(Assuming hexagonal shape will have 6 (SIX) sides of equal length).
_________________________________________________
Explanation:
__________________________
Let us assume you meant to write that the: "...new park, in the shape of hexagon, will have 6 (six) side of equal length."
_________________________________________
From the coordinates given, we can infer that this is a "regular" hexagon. 
_______________
Here is one way to solve the problem:  Find the length of ONE side of the hexagon.
_____________________
Let us choose the following coordinates: (18,0), and (6.5, 5).  Let the distance between these points , which would equal ONE side of our hexagon, represent "c", the hypotenuse of a right triangle. We want to solve for this value, "c".
_____________________
Let the distance on the x-axis, from (6.5, 0) to (18.5, 0);  represent "b", one side of a right triangle.  
   → We can solve for "b" ;  → b = 18.5 - 6.5 ;  → b = 12 .
___________________________________________________'
Let the distance from (6.5, 0) to (6.5, 5) ; represent "a"; the remaining side of the right triangle.
__________________
 → a = y₂ - y₁ = 5 - 0 = 5 ; 
________________________________________________
{Note: We choose the particular coordinates, including "(6.5, 0)", because the distances between the coordinates chosen form a "right triangle";  (with "c", representing a "hypotenuse", or "slanted line segment"; which would be also be "ONE line segment of the given regular hexagon", which is our answer, because each line segment is the same values, so we only have to find the value of ONE line segment, or side, of the hexagon.).
    When considering the given coordinates: "(6.5, 5)", and "(18.5, 0)", a "right triangle" can be formed at the coordinate, "(6.5, 0),

By choosing this particular letters (variables) to represent the sides of a "right triangle", we can solve for the "hypotenuse, "c", using the Pythagorean theorem for the sides of a right triangle: 
______________________
 → a² + b² = c² ; in which "c" represents the hypotenuse of the right triangle
and "a" represents the length of one of the other sides; and "b" represents the length of the remaining side. (Note: All triangles have three sides).
_____________________________
We have: a = 5 ;  b = 12 ; → Solve for "c" ; 
______________________________________
 → a² + b² = c² ;  ↔  c² = a² + b²  ; Plug in the known values for "a" & "b" ;
___________________________________
→ c² = a² + b² ;  → c² = 5² + 12² ;

→ c² = 25 + 144 = 169 ;   →  c²  = 169 ;
_________________________________________
→ Take the square root of each side; to isolate "c" on one side of the equation; and to solve for "c" ;
______________________________
 →  c²  = 169 ;  √(c²) = √(169) ;  →  c = ± 13; 
 
 → ignore the negative value; since the side of a polygon cannot be a negative number; 
________________________________
 →  c = 13 ; The answer is: 13 units.

What is the equation of a line that is perpendicular to y = 3 x − 2 and passes through the point ( 6 , 8 )
Zolol [24]

The slope of the given line is 3.  Therefore, the slope of any line perpendicular to y = 3x - 2 is the negative reciprocal of 3, which is m = -1/3.

Starting with the point-slope equation of a straight line, obtain the specific equation applicable here by substituting the givens:  m = -1/3, h = 6 and k = 8):

y - k = m (x - h) becomes y - 8 = (-1/3)(x - 6) (answer).

This could, if you wish, be rewritten in some other format.
