(- 1 + √3)/2
rationalise the denominator by multiplying the numerator/denominator by the conjugate of the denominator.
the conjugate of 1 + √3 is 1 - √3
(1 - √3)/(1 + √3)(1 - √3) = (1 - √3)/( 1² - (√3)²) = (1 - √3)/(1 - 3) = (1 - √3)/(- 2)
multiply numerator/denominator by (- 1)
=(-1 +√3)/2
Answer: SOLUTION: find three cosecutive odd integers such that the sum of the least and greatest is 78. Let x, x+2, x+4 b the 3 consecutive odd integers. 37, 39, 41.
Step-by-step explanation: look above lol hope this helps u gud luk
The best way to do this is to set up a proportion
30 20
---- = -----
0.5 x
then cross multiply and divide
20 × 0.5 = 10/30=1/3
he needs 1/3 tank of gas to drive 20 miles
