the sum of the three given sides is ... 7x + 2xy + 5y
subtract from the total length to find the missing side
your 1st answer seems correct
... how did you get the 2nd one?
The total length of the walking path is 8x+xy+6y. Find missing side length. Other side lengths are:
2x-xy+3y
3x-2xy+3y
2x+5xy-y
I know to subtract but I think I’m still doing it wrong. I got two different answers. I got x-xy+y and I got x+3xy+11y. I’m not sure where my mistake is . Please help
