Write an equation to find the value of so that ench pair of polygons has the same perimeter. Then solve.

x+6
x+9
x+3

x+4
x+1

5x
5x
5x
5x
5x
5x

x+14
x+17
8x+9

Step-by-step explanation:

Perimeter of both the polygons are same.    

Sum of the sides of the triangle = Sum of the sides of the rectangle    

Therefore, the equation will be,  

(x + 6) + (x + 9) + (x + 3) = 2(x + 1) + 2(x + 4)

16). Sum of the measures of all sides of the hexagon = sum of all sides of the triangle    

Therefore, the equation will be,  

 6(5x) = (x + 14) + (x + 17) + (8x + 9)
