3x^3+12x^2+3x
The GCF would be 3x, you can factor out a 3x
3x(x^2+4x+3)
You can further factor the problem...
3x(x+3)(x+1)
Another equivalent form can be made if you simply distribute 3x into x+3
(3x^2+9x)(x+1)
Answer:
There are no graphs...
Step-by-step explanation:
<u>Answer:
</u>
An inlet pipe on a swimming pool can be used to fill the pool in 33 hours. Time it will take to fill the pool = 748 hrs
<u>Solution:
</u>
Let x = time it will take to fill the pool
= work rate of inlet pipe
= work rate of drain pipe
Using the formulae
Volume of flow=work rate time
Let us assume complete time of pool to fill = 1
Remaining fraction of pool to be filled =
Time it will take to fill the pool = 748 hrs
