Answer:
r = -1 or r = 5/3
Step-by-step explanation:
(2k - 1)/(k + 1) = (3k + 1)/(2k - 1)
(2k - 1)^2 = (k + 1)(3k + 1)
4k^2 - 4k + 1 = 3k^2 + 4k + 1
k^2 - 8k = 0
k(k - 8) = 0
k = 0 or k = 8
For k = 0,
(2k - 1)/(k + 1) = -1/1 = 1
For k = 8,
(2k - 1)/(k + 1) = 15/9 = 5/3
I think it will be like this
37.5% : 100%
3 : 8
<em>sorry</em><em> </em><em>if</em><em> </em><em>im</em><em> </em><em>wrong</em>
This is 60 because if you were to 12 times 1 you would get 12 then multiply by 5 and you get 60. Now to check your answer do 12 divided by 12 which gives you 1 and do 60 divided by 12 gives u 5. Therefore the answer is 60cm hope this helps!
