hello, so i am having my Algebra regents tomorrow.
I was just confused on the first question. If you can reply asap,
that would be great. i got confused on 3:14, the part where you made in
rectangle. I understand where the 12 came from, but i didn't really understand where you got 10 from ( for the width of the rectangle. ) It would really help if you responded
thank you.
