Factor completely<br> 486+108x+6x^2<br><br> Thank you!
viktelen [127]

Answer:

6(x + 9) (x + 9)

or

6 (x+9)^{2}

Step-by-step explanation:

468 + 108x + 6x^{2} \\6x^{2} +108x + 468

Greatest common factor of 6, 108, and 486:

6 x 1 = 6

6 x 18 = 108

6 x 81 = 486

GCF: 6

so:

6(x^{2} +18x +81)

x^{2} +18x + 81

factors to:

(x + 9) (x + 9)

because:

9 x 9 = 81

9 + 9 = 18

So:

It factors completely too:

6(x + 9) (x + 9)

or

6 (x+9)^{2}

Erica's travel plans include 4 independent flights. The chance of a flight being on time is 90%. What is the probability that al
e-lub [12.9K]

Since the chance of a flight being on time is 90%. The probability that all of Erica's flights will be on time is B 66%.

To answer the question, we need to know what probability is

<h3>What is probability?</h3>

This is the likelihood for an event to occur. It is given by

P(event) = number of required outcomes/total number of outcomes

Now, given that Erica's travel plans include 4 independent flights. The chance of a flight being on time is 90%. So, P(flight) = 90%. Since they are indepent, we multiply their probability.

<h3>Probability that all of Erica's flights will be on time</h3>

So, the probability that all of Erica's flights will be on time is P(on time) = P(flight) × P(flight) × P(flight) × P(flight)

= [P(flight)]⁴

= (90%)⁴

= (0.9)⁴

= 0.656

≅ 0.66

= 66%

So, the probability that all of Erica's flights will be on time is B 66%.
