We use the above identity: (a+b) 3 =a 3 +3a 2 b+3ab 2 +b 3 . Take a=2x and b=3y and we get

(2x+3y) =(2x) 3 +3(2x) 2 (3y)+3(2x)(3y) 2 +(3y) 3 =8x 3 +36x 2 y+54xy 2+27y 3

Answer:

See step-by-step explanation.

Step-by-step explanation:

For the first question, you simply put an EMPTY circle above 2 and draw an arrow from it all the way down to -3. The reason why we put an empty circle is because there is no equal sign below it.

For the second question, you put a FILLED circle above 4 and draw an arrow from it all the way down to -3. The reason why we use a filled circle is because x is less than OR equal to 4.
