A square wire frame is cut open and then bent to form a regular hexagon. Each side of the square as well as of the hexagon formed is a whole number (when measured in cm). Which of these could be the perimeter of the hexagon? give correct Ans with explanation

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72

6 equilateral triangles

1) the property is   ixi = a ⇔x = a   o x = -a

4(x-5)+3= 15⇒4x-20+3 = 15⇒4x-17= 15⇒4x = 15+17⇒4x = 32⇒x =32/4= 8

4(x-5) +3= -15⇒4x-20 +3 = -15⇒4x-17= -15⇒4x =-15+17⇒4x = 2⇒x =2/4= 1/2

the values are x =8 and x = 0,5
