A new cruise ship line has just launched 3 new ships: the Pacific Paradise, the Caribbean Paradise, and the Mediterranean Par

topjm [15]

Let the number of deluxe that Pacific has be x
the number that Caribbean has will be (x+18)
the number that Mediterranean has will be (3x-25)
total b=number of deluxe in the 3 ships will be:
x+(x+18)+(3x-25)
5x-7=928
5x=928+7
x=935/5
x=187
Hence the Pacific has 187, Caribbean has 187+18=205, Mediterranean has (3*187-25)
=534

You take the three zeros and put them back with the x s

(x-6)(x+5)(x-2) they are reversed when you put them back in

multiply the first two and get $x^2+5x -6x-30(x-2)$
simplify to $x^2-x-30(x-2)$

Multiply it out again and get $x^3-x^2-30x-2x^2+2x+60$
finally simplify and get $x^3-3x^2-28x+60$

So the answer is the first one
