the coordinates of the endpoints of PQ are P (-3,-2) and Q (9,2) . M is the midpoint of PQ and N is the mind point of MQ . what are the coordinates of N

exactly you go it

step-by-step explanation:

the answer is  

a.

4,624π mm2

step-by-step explanation:

      2

  2 is to go somewhat to the top right of a because it is squared    

v= a h/3

\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?
