\3. yes the presentation (i.e. odd numbers being written as differences of two squares) is possible for all odd natural number however the presentation may not be unique. for example,  57=112−82=292−28257=112−82=292−282.

\4. 2 can't be written as a difference of two squares because 4-1=3 and 1-1=0 and the difference of squares grows to integers larger that 3.

can i get some in proving questions 1 and 2?

a: kite

step-by-step explanation:

figure lmno is located at l (1, 2) m (3, 2), n (3, 0), and o (0, −1). use coordinate geometry to best classify quadrilateral lmno.

answer is b

hope you get this one right.
