What is formula of sum of cubes and difference of cubes?</h3>
Formula of sum of cubes and difference of cubes are following
(a)
by comparison with formula we can say that this is neither sum or nor difference of cubes.
(b)
by comparison with formula we can say that this is neither sum nor difference of cubes.
(c)
we can say that this is neither sum nor difference of cube as it's difference of squares.
(d)
by comparison with formula this is equal to
Hence this is sum of cubes
(e)
by comparison with formula we can say that this is neither sum nor difference of cubes.
By comparing all the options with the formula of sum of cubes and difference of cubes we get that is sum of cubes

Answer:
C. (3,6)
explenation
We are given that,
The point (-3,-6) is transformed by the rule .
That is, the point is reflected across y-axis and then reflected across x-axis.
That is, the rule for the transformation is (x,y) → (-x,y) → (-x,-y).
So, we get,
(-3,-6) → (3,-6) → (3,6)
Thus, the co-ordinates of the image are (3,6).
So, option C is correct.
Let <em>V</em> be the volume of the tank. The inlet pipe fills the tank at a rate of
<em>V</em> / (5 hours) = 0.2<em>V</em> / hour
and the outlet pipe drains it at a rate of
<em>V</em> / (8 hours) = 0.125<em>V</em> / hour
With both valves open, the net rate of water entering the tank is
(0.2<em>V</em> - 0.125<em>V </em>) / hour = 0.075<em>V</em> / hour
If <em>t</em> is the time it takes for the tank to be full, then
(0.075<em>V</em> ) / hour • <em>t</em> = <em>V</em>
Solve for <em>t</em> :
<em>t</em> = <em>V</em> / ((0.075<em>V</em> ) / hour)
<em>t</em> = 1/0.075 hour
<em>t</em> ≈ 13.333 hours
