Ella is 6 years younger than Amanda.  Zoe is twice as old as Amanda.  The total of their ages is 54.  Which equation can be used to find Amanda's age?
A.)  x + (x - 6) + 2(x - 6) = 54
B.)  x - 6x + (x + 2) = 54
C.)  x - 6 + 2x = 54
D.)  x + (x - 6) + 2x = 54
E.)  2(x + 6) + (x + 6) + x = 54

(2 - x²)(3x + 1) is equivalent to:
A.)  6x - x² - 3x³
B.)  2 - x² - 3x³
C.)  2 + 6x - 4x²
D.)  2 + 6x + x² - 3x³
E.)  2 + 6x - x² - 3x³
