Answer:
216 x^3 - 540 x^2 + 450 x - 125 = (6 x - 5)^3
Step-by-step explanation:
The first one cannot be a perfect cube, since the first term contains x^2 and not x^3.
the second one is not a perfect square (the coefficient of the middle term should be an even number: "-90")
The third expression is the perfect cube as shown.
Answer:
Step-by-step explanation:
The profit function is:
Where
P is the profit
and
d is the number of units sold
Now, there is a 50% increase in number of units sold, so d will become:
50% = 50/100 = 0.5
d + 0.5d = 1.5d
So, we have to replace "d" with "1.5d" in the function, which makes it:
From the equations shown, last answer choice is correct.
