(0101 UC) Which number line best shows how to solve -2- (-4)? 10 -2 0 2 4 6. 8 10 -10 B 2 0 2 8 10 10​

Cis your correct answer

None of those are technically correct. 9.7 x 104 is actually 1,008.8, but if that answer was a choice, it would be that one. if you meant 9.7 times maybe a thousand or more or divided by 10 or more, than the answer choices would be correct, but other than that, they actually arent.

The correct answer is b

Prove that every odd prime number can be written as a difference of two squares.prove also that this presentation is unique.is such presentation possible if p is just an odd natural number? can 2 be represented this way?

answers

\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?
