Answer:
(3x + 5)(9x^2 - 15x + 25)
Step-by-step explanation:
27x^3 + 125
= (3x)^3 + 5^3
= (3x + 5) ((3x)^2 - (3x)(5) + 5^2)
= (3x + 5)(9x^2 - 15x + 25)
FYI: a³ + b³ = (a + b)(a² – ab + b²)
Answer:
The correct answer is B
Step-by-step explanation:
Answer:
0.45 = 45% probability that the member uses the golf course but not the tennis courts
Step-by-step explanation:
I am going to solve this question using the events as Venn sets.
I am going to say that:
Event A: Uses the golf courses.
Event B: Uses the tennis courts.
5% use neither of these facilities.
This means that 
75% use the golf course, 50% use the tennis courts
This means, respectively, by:

Probability that a member uses both:
This is
. We have that:

So

What is the probability that the member uses the golf course but not the tennis courts?
This is
, which is given by:

So

0.45 = 45% probability that the member uses the golf course but not the tennis courts
