Help fast, 45 points on the line, Which equation correctly applies the distributive property?

​2.4⋅(−3.4)⋅(−1.25)=−3.4⋅2.4⋅(−1.25 )​

​−2.5⋅(4⋅3.67)=(−2.5⋅4)⋅3.67​

​(42⋅3.5)+(42⋅1.3)+(42⋅5.2)=42+(3.5 +1.3+5.2)​

​−3⋅(6.48)=(−3⋅6)+(−3⋅0.4)+(−3⋅0.08 )

true

step-by-step explanation:

i think its a.

hope this

\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?
