n^{16} and 9 are the squares of, respectively, n^8 and 3.

So, using

a^2-b^2=(a+b)(a-b)

we have

n^{16}-9=(n^8+3)(n^8-3)

In factored form please help
Brilliant_brown [7]

Answer:

3rd option

Step-by-step explanation:

\frac{3x^2-3}{x^2-5x+4} ( factorise numerator and denominator )

3x² - 3 ← factor out 3 from each term

= 3(x² - 1²) ← x² - 1 is a difference of squares and factors in general as

a² - b² = (a - b)(a + b)

x² - 1

= x² - 1²

= (x - 1)(x + 1) , then

3x² - 3 = 3²(x - 1)(x + 1) ← in factored form

--------------------------------

x² - 5x + 4

consider the factors of the constant term (+ 4) which sum to give the coefficient of the x- term (- 5)

the factors are - 1 and - 4 , since

- 1 × - 4 = + 4 and - 1 - 4 = - 5 , then

x² - 5x + 4 = (x - 1)(x - 4)

then

\frac{3x^2-3}{x^2-5x+4} = \frac{3(x-1)(x+1)}{(x-1)(x-4)} ← in factored form

A car drives 40 miles on local roads at 20 mph, and 180 miles on the highway at 60 mph, w Your dinner bill is $25 before tax. Th
Anastasy [175]

Answer and Step-by-step explanation:

Let's~solve~your~problem!

<em><u>Formula : </u></em>

<u></u>speed=\frac{distance}{time}

<em><u>Solving for time:</u></em>

Time~taken~to~cover~40~miles~on~local~ roads~= \frac{40}{20}  = 2~hours

Time~taken~to~cover~180~miles~on~the~highway~= \frac{180}{60}=3~hours

Total~Time~=~5~hours

<em><u>Solving for distance:</u></em>

<em><u /></em>Total~Distance=40 + 180 = 220<em><u /></em>

<em><u /></em>

<em><u>Average speed:</u></em>

<em><u /></em>\frac{Total~distance}{Total~time}  = \frac{225}{5}  = 44~miles~per~hour<em><u /></em>
