%28x%2B2%29%2B%283x%2B1%29%2B%28x%2B7%29=140

5x%2B10=140

x%2B2=28

x=26---------------this may mean the side lengths are 28, 79, and 33.
Check to be sure each of these is true:
system%2828%2B79%3E33%2C79%2B33%3E28%2C28%2B33%3E79%29
If any is false, then the triangle with those sides is no good.

saying that this problem is a FAKE.


Do not post it again.


Also, learn that "pirimiter" is, actually, perimeter,

and "tringle" is, actually, triangle.


Use and write the words correctly (!)
