simplify: 7 -( 3 x +( - 2 Y + 3 Z -( 3 Y + 5 Z) + 8 )- (3 y ^2 + 7 x )+ 9) Ans fast plz urgent full ans plzzzzzzz

Answer 1

Answer:

= 8 - 10x + 5y + 2z - 3y^2

Step-by-step explanation:

7 - (3x + (-2y + 3z - (3y + 5z) + 8) - (3y^2 + 7x) +9

= 7 - (3x - 2y + 3z - 3y - 5z +8 ) - 3y^2 - 7x +9

= 7 - 3x + 2y - 3z + 3y + 5z - 8 - 3y^2 -7x + 9

= 8 - 10x + 5y + 2z - 3y^2
