Zappos has them for a pretty reasonable price at: http://www.zappos.com/asics-gel-nimbus-12-shoes/CK_XAeICAQE.zso?t=asics%20gel%20nimbus%2012&s=recentSalesStyle/desc Amazon has quite a few pairs too and they have very good reviews there.
You can buy asics numbus 12 shoes from ebay.com and amazon.com and they should vary in cost from 65 - 75. There are some other websites you could try, such as startfitness.com and runnersworld.co.uk
To find the price of one pair of socks when 12 pair sell for $5.79, you would divide the price by the number of pairs of socks in the package. So, dividing $5.79 by 12, you would find that one pair of socks would be $.482, which most retailers would round down to $.48/pair.
Sorry, but there aren't any trainers with a Vespiquen in Pokemon Black 2. I guess you have to find it in the shaking grass in route 12 or Lostlorn Forest.
f(2) = -2 + 12 = 10 so the ordered pair is (-2, 10).

I'm not sure exactly what you mean by "pair of no.12" There is no factor pair of 12 that has a GCF of 6. There is a pair of factors of 12 (6 and 12) that have a GCF of 6. There is a pair of numbers that add up to 12 (6 and 6) that have a GCF of 6. 6 and any multiple of 6 have a GCF of 6. Any multiples of 6 that differ by 6 have a GCF of 6.
11 and 12 are a factor pair of 132.
Amazon.com sells the Mizuno Wave Creation 12 trainers (http://www.amazon.com/Mizuno-Mens-Wave-Creation-Running/dp/B004G604O6), and the product page I have linked to also provides customer reviews. If it is the women's version you are interested in, Amazon sells those as well, and likewise provides reviews.
