Answer:
The equivalent expression is: (6x + 5)*(6x - 5)
Step-by-step explanation:
This expression is called the difference of two squares.
It has the following format: 
It is factored as: 
In this question:

So
, then 
, then 
So
The equivalent expression is: (6x + 5)*(6x - 5)
It takes 3 pumps 16 hours to empty a tank
Meaning it takes 48 hours for one pump by its self
So if there are 4 pumps
48/4 it would take them 12 hours
They would need to work 12 hours to do it in 1 day
well, since we know that there are 180° in π radians, how many degrees will it be in 345°?

If it is 35% off, then u r paying 65%...
0.65(128.25) = 83.36....this is without the tax
and there is a 4% sales tax....
83.36 * 1.04 = 86.69 <====
Step-by-step explanation:
the answer is 744..........
