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:
See below in bold.
Step-by-step explanation:
Factored form:
f(x) = -5(x + 7)(x - 9)
Standard form:
f(x) = -5(x^2 + 7x - 9x - 63)
f(x) = -5(x^2 - 2x - 63)
f(x) = -5x^2 + 10x + 315.

Answer:
3 times the length of the corresponding sides of the original rectangle.
Step-by-step explanation:
Because the length measures have not been given for the original rectangle, the exact measures of A'B'C'D' can not be found. But, because the factor is 3, then the side lengths have been tripled. For example, side A'B' would be 3 times the length of side AB. Side C'D' would be 3 times the length of side CD.
