Answer:
Step-by-step explanation:
hello :
3b^4−6b^2+27b = 3b(b^3-2b+9)
For

,

, all the more

, therefore no solution.
For

, we have

. Obviously that' false.
For

both

and

, where

, belong to the range

, then

belong to the range

.
Those ranges don't have a common part, therefore, again, no solution.
So, the equation

doesn't have a solution.
Answer:
The answer is C (7)
Step-by-step explanation:
The graph gives the equation Y=12x, so by doing 87/12 you get 7.25 which is closest to 7 giving you the answer.
Answer:
D) 5 7/9
Work Shown:
-52/-9 = 5 7/9 = 5.7777777778
31 in total and the smaller one has 13. So just subtract 31-13 and it means there are 18 balls in the larger bag
