24 kilometres = 14.91 miles (approx)
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
2 miles = 10,560 feet
There are 10,560 Feet in 2 Miles.
2.5 miles
One kilometer is equal to 0.621371 miles. So, to convert 4 kilometers to 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.
2.49 miles
-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
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
