I would say that the third one is false.
I got 6x+3
The three equations are:
(2x-6) + (3x+1) + (x+8) =perimeter
2x+3x+x/1x=6x
-6+1+8= 3
Even numbers are divided by two
Even numbers are easier to cope with in math problems
There are only odd prime numbers
A) $55.00
65 yards for $85.00 subtract
20 yards for $30.00
85-30=55
