how long?

the side of a quadrilateral are arstcutive numbers if the perimeter is 162. how long is each side?

What is "arstcutive" numbers mean? Do you mean consecutive numbers? if so, then the perimeter is: 39, 40, 41, 42 units each, for a total of 162.

Let's see how the guest got this answer....

Let n be one side.......then n + 1  = the second side, n + 2 = the third side, and n + 3  = the fourth side........so we have

n + [n + 1] + [n + 2] + [n + 3]  = 162  simplify

4n + 6  = 162    subtract 6

4n = 156    divide both sides by 4

n = 39

And n + 1 = 40

And n + 2 = 41

And n + 3 = 42
