If PQRS is a parallelogram, what is the value of y? S R 13 P 11 o O A. 44 O B. 60 O C. 52 O D. 26 E. 48 O F. Cannot be determined​

i believe so, according to my "strange" way of figuring out weird math problems like this.

the rate of change is 25

\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?
