Hello from MrBillDoesMath!
Answer:
The two expressions are equal for all x,y. In fact they are an identity.
Discussion:
(x +2 ) (y + 3) = xy + 3x + 2y + 6 (left hand side of =)
xy + 2y + 3(x+2) = xy + 2y + 3x + 6 (right hand side of =)
As the boldfaced values are equal the left hand side equals the right hand side! Hence the two expressions are equal for all x,y. In fact they are an identity.
Thank you,
MrB

Step-by-step explanation:
Perimeter = sum of all sides of a regular polygon = the number of sides*length of a side
Length of a side of the given regular hexagon = 3x + 5
Perimeter of hexagon = 6(3x + 5) = 6(3x) + 6(5) = 18x + 30
Length of a side of the given regular pentagon = 4x - 1
Perimeter of pentagon = 5(4x - 1) = 5(4x) - 5(1) = 20x - 5
Since we are told that the perimeter of the regular hexagon is the same as that of the regular pentagon, therefore:
18x + 30 = 20x - 5
Solve for x.
Subtract 20x from both sides
18x + 30 - 20x = 20x - 5 - 20x
-2x + 30 = -5
Subtract 30 from both sides
-2x+ 30 - 30 = -5 - 30
-2x = -35
Divide both sides by -2
x = -35/-2
x = 17.5
Length of a side of pentagon = 4x - 1
Plug in the value of x
4(17.5) - 1 = 70 - 1 = 69
length of a side of the pentagon = 69
