1 meter :12 cm
1 cubic meter = 1 x 1 x 1 : 12 x 12 x 12 = 1,728 cubic cm.
Okay first make sure you change negative 8 to a positive 8.
Set the problem up 8 -11 -49 899 -2506

Your answer will be
-11x^3 - 137x^2 - 197x - 4082
The answer to your question is 7.375
The smallest possible value of z is the denominator of the reduced fraction x/y. We note the prime factors of the members of set y are
... 2², 7, 2³, 3²
so if there are any even members of set x, the fraction can be reduced to something divided by 2. The number 6 in set x is even, so we have
... 6z/4 = 6·2/4 = 3 (an integer) when z=2
The lowest possible value of z is ...
... B) 2
