12x+7x+8y+12^2+y+12=19x+9y+24^2
Explanation:
The formula isnt correctly written, it should state:

You have to start from
and end in a³+b³. On your first step, you need to use the distributive property.

This is equal to

Note that the second term, -a²b, is cancelled by the fourth term, ba², and the third term, ab², is cancelled by the fifht term, -b²a. Therefore, the final result is a³+b³, as we wanted to.

=4
A, c, and e are the correct answers
Easiest ways to solve them are to take the denominator and numerator and and divide the one you are asked to use to answer and divide and see if it works on both.
Example: first 105 / 15 = 7 ) Then: 105 / 7 = 15
119 ) 119 / 7 = 17
Hope I helped. :D
