im so confused pls help
you know that the perimeter is the sum of all the sides, right? So now you have
each long side is 6 more than 2x-3 or 2x+3
2x-3 + 2x+3 + 2x+3 = 33
6x+3 = 33
6x=30
x = 5
So, each long side is 2(5)+3 = 13
Check: 7+13+13 = 33
each long side is 6 more than 2x-3 or 2x+3
2x-3 + 2x+3 + 2x+3 = 33
6x+3 = 33
6x=30
x = 5
So, each long side is 2(5)+3 = 13
Check: 7+13+13 = 33
