Number 8
the perimeter of rectangle = the perimeter of hexagon
2l + 2w = the sum of the sides on hexagon
Input what are given from the image
2l + 2w = the sum of the sides on hexagon
2(2x + 5) + 2(x) = 2x - 6 + 0.5x + 1.5x + 3x + 1 + 2.5x + 1.5x
Simplify the left side and the right side
4x + 10 + 2x = 11x - 5
6x + 10 = 11x - 5
This is the equation
Number 9
Solve the equation
6x + 10 = 11x - 5
6x - 11x = -5 - 10
-5x = -15
x = -15/-5
x = 3
The solution is x = 3
