What is the answer for 2n^2-8n=-9 ?

lbvjy [14]

2n^2-8n=9

divide by 2

2(n^2-4n) =9

add (4/2)^2 =4 to each side completing the square

(n^2-4n+4 ) =9/2+4

(n-2)^2 = 9/2+8/2

(n-2)^2 =17/2

take the square root of each side

n-2 = +-sqrt(17/2)

add 2 to each side

n = 2+- sqrt (17/2)

Answer:2+ sqrt (17/2),2- sqrt (17/2)

$\frac{1}{20}$

Explanation:

Suppose there are x patron in the Joes restaurant.

$\frac{1}{4} ^{th}$ patron are male

$\frac{1}{5} ^{th}$ patron are outside of the town.

Now we need to find the proportion of male and out of town.

In order to find out the proportion, we will multiply both the fractions together.

$\frac{1}{4}* \frac{1}{5}$

In case of fraction multiplication, we will multiplying both numerator together and denominator together.

= $\frac{1*1}{4*5}$

= $\frac{1}{20}$

Final answer is 1/20.

I hope its help you.
