A kilometer is 0.62 miles. So 4k is 2.48 miles
k=-2
-4k + 10 - k + 2 = 2k + 4k + 18Combine all the 'k' terms on the left side:-5k + 10 + 2 = 2k + 4k + 18Combine all the 'k' terms on the right side:-5k + 10 + 2 = 6k + 18Combine the numerical terms on the left side:-5k + 12 = 6k + 18Add 5k to each side:12 = 11k + 18Subtract 18 from each side:-6 = 11kDivide each side by 11:k = -6/11
Well, isn't that just a happy little equation we have here! When you multiply 4k by k, you simply multiply the coefficients (4 and 1) to get 4, and then add the exponents of k, which gives you k^2. So, 4k x k equals 4k^2. Just remember, there are no mistakes in math, only happy accidents!
2 miles = 10,560 feet
2.5 miles
4,000 meters. Almost 2 and a half miles.
4k (kilometers) = 2.48548477 miles and 3200 meters = 1.98838782 miles. So, a 4k race is about 1/2 of a mile farther than a 3200 meter race.
-4k-2=10 -4k=10+2 -4k=12 k=-3
No,1 kilometer = 0.621371192 miles
2.5 miles approx.
4k-7 = 7 4k = 14 k = 3.5 or k = 7/2
No,1 kilometer = 0.621371192 miles
4k
A kilometer is 0.62 miles. So 4k is 2.48 miles
x =√k+√k+√k…… ectx² = k + xx² - x = kx² - x + (1/2)² = k + (1/2)² factorise x² - x + (1/2)²(x + 1/2)² = k + 1/4(x + 1/2)² = (4k + 1)/4x + 1/2 = ± √(4k + 1)/2x = 1/2 ± √(4k + 1)/2it obviously has to be positivex = 1/2 + √(4k + 1)/2x = (1 + √(4k + 1))/2
If by K2 you are not referring to the mountain, the distributive property of multiplication tells us K * 2 = 2 * K.Therefore: K2 + 2K + 4K = 2K + 2K + 4K = 8K
