Plz someone help me..!!
c. In the given figure, M and N are
mid-points of AB and AC
respectively. P is a point on MN.
prove that AP = PD.

Step-by-step explanation:

M and N are  mid-points of AB and AC  respectively.

So, MN // AB {mid point theorem}

P is on MN

Therefore,  MP//BD  

In ΔABD,

M is midpoint of AB and MP//BD

As per converse midpoint theorem,

P is the midpoint of AD

AP = PD

the answer is 8.64

step-by-step explanation:

\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?
