Answer:
4+4=100000 :) thank me later
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)
Answer:
37
Step-by-step explanation:
We start by reducing the ratio to its smallest value. This is the same as 1:14
We know from the question that the number of apple eater takes the 14 ratio part. We can make the calculations for the total number first then make a subtraction to get the number of apple eaters.
Firstly, we add the ratios together:
1 + 14 = 15
Let the total number of reindeers be T
14/15 * T = 517
T = (15 * 517)/14 = 554
To get the the number of apple loving Reindeers, we then subtract.
This is 554 - 517 = 37
