Answer:
The top is 5
The right side is 5
The bottom is 2x = 2*5 = 10
The left is 5-2 = 3
Step-by-step explanation:
The perimeter is the sum of the sides
x+x+ 2x + x-2 = 23
Combine like terms
5x-2 = 23
Add 2 to each side
5x-2+2 = 23+2
5x = 25
Divide each side
5x/5 = 25/5
x = 5
The top is 5
The right side is 5
The bottom is 2x = 2*5 = 10
The left is 5-2 = 3
