It is a acute I think that is the answer I am in 7th grade so I don’t really know
Answer:
A) (2x − 7) (4x² + 14x + 49)
C) (3x + 5) (9x² − 15x + 25)
Step-by-step explanation:
Sums and differences of cubes factor as:
a³ + b³ = (a + b) (a² − ab + b²)
a³ − b³ = (a − b) (a² + ab + b²)
8x³ − 343 is a difference of cubes.
(2x)³ − 7³
(2x − 7) (4x² + 14x + 49)
27x³ + 125 is a sum of cubes.
(3x)³ + 5³
(3x + 5) (9x² − 15x + 25)
Answer: The probability that both televisions work : 0.5329
The probability at least one of the two televisions does not work : 0.4671
Step-by-step explanation:
Given : The total number of television : 11
The number of defective television : 3
The probability that the television is defective : 
Binomial distribution formula :-
, where P(X) is the probability of getting success in x trials, p is the probability of success and n is the total trials.
If two televisions are randomly selected, then the probability that both televisions work:
The probability at least one of the two televisions does not work :
78.00 = 59.99+0.10x
10.01=0.10x
x= 180.1 so she can send 180 texts plus the 100 free ones for a total of 280 texts
double check: 180 x 0.10 = 18.00 + 59.99 = 77.99
