If x=2+√3,then find the value of x-1/x

Answers

A :-) x = 2+_/3
x-1/x = 1/2+_/3
( rationalize the denominator )
x-1/x = 1/2+_/3 x 2 -_/3/2 - _/3
[ ( a + b ) ( a - b ) = a^2 -b^2 ]
x-1/x = 2 - _/3/( 2 )^2 - ( _/3 )^2
x-1/x = 2 - _/3/4 - 3
x-1/x = 2 - _/3/1
x-1/x = 2 - _/3
x-1/x = ( 2+_/3 ) ( 2 - _/3 )
x -1/x = ( 2 )^2 - ( _/3 )^2
( x = 2+_/3 )
x-1/x = 4 - 3
x-1/x = 1

There are 63 new houses being built in a neighborhood. last month 1/3 of them were sold. this month 2/7 of the remaining houses were sold. How many houses are left to be sold?

Answers

Answer: 49 houses

Step-by-step explanation:

63 x 1/3 =63/3= 21 houses were sold last month. 63 - 21 = 42 houses remained unsold last month. 42 x 2/3 =[42 x 2] / 3 = 84 / 3 = 28 houses were sold this month. 21 + 28 = 49 houses sold altogether.
