Answer:
378 marbles are blue, and 270 marbles are red
Step-by-step explanation:
The total number of ratio units must be multiplied by 6 to get the total number of marbles. Hence the number of blue marbles is 63×6 = 378, and the number of red marbles is 45×6 = 270.
(12x3 - 14x2 - 40x) / (2x-5)
Rewriting we have:
(2x (2x-5) (3x + 4)) / (2x-5)
We simplify similar terms:
2x * (3x + 4)
We rewrite:
6x2 + 8x
Answer:
The simplified expression is given in this case by:
6x2 + 8x
