What does 3-4[9-(3y-4)] simplify to?

(3y−40)

Rewrite  ( 3y − 4 ) 2 ( 3y - 4 ) 2  as  ( 3y − 4 ) ( 3y − 4 ) ( 3y - 4 ) ( 3y - 4 ) .

( 3y − 4 ) ( 3y − 4 ) ( 3y - 4 ) ( 3y - 4 )

Expand  ( 3y − 4 ) ( 3y − 4 ) ( 3y - 4 ) ( 3y - 4 )  using the FOIL Method.

3y (3y) + 3y ⋅ − 4 − 4 ( 3y ) − 4 ⋅ − 43y ( 3y ) + 3y ⋅ - 4 - 4 ( 3y ) - 4 ⋅ -

Simplify and combine like terms.

Simplify each term.  9y 2 − 12y − 12y + 16 9 y 2 - 12 y - 12 y + 16

Subtract  12y 12y  from  − 12y - 12y . 9y2 − 24y + 16

So 3-4[9-(3y-4)] simplfied is (3y−40).

the answer will be the last one
