... below. (circle)10x-2 (square) 3x-5. Because the gardens have the same perimeter, the following equation can be used to solve this situation.10x - 2 = 4(3x-5)Which of the following represents the number of feet of fencing that Clarissa bought? please help. Thanks.

10x - 2 = 4(3x-5) The rule is you can do any valid operation on both sides of an equation and it will still be equal. First evaluate the parentheses.
10x - 2 = 12x - 20 Now add 2.
10x = 12x - 18 Subtract 12x.
-2x = -18 Divide by -2.
x = 9
The presentation does not explain well enough to calculate a perimeter. the given equation does not make any sense. Math is only valid when it describes reality.
