You need to make 3200 gallons of 42% acidic solution. They have 36% acidic solution and a 54% solution. How many gallons of each type are needed to make 3200 gallons of 42% acidic solution

y-3=-3/2(x+4)

ur very much welcome

the answer to this would be 5x^3-6x^2-24 over 3x^2

\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?
