Answer:

2 + \sqrt{3}

Step-by-step explanation:

\dfrac{1}{\sqrt{4} - \sqrt{3}} =

= \dfrac{1}{2 - \sqrt{3}}

= \dfrac{1}{2 - \sqrt{3}} \times \dfrac{2 + \sqrt{3}}{2 + \sqrt{3}}

= \dfrac{2 + \sqrt{3}}{(2 - \sqrt{3})(2 + \sqrt{3})}

= \dfrac{2 + \sqrt{3}}{4 - 3}

= \dfrac{2 + \sqrt{3}}{1}

= 2 + \sqrt{3}

The area of a rectangle is 14 yd2 , and the length of the rectangle is 3 yd less than twice the width. find the dimensions of th
ExtremeBDS [4]
Let x be the width 
2x-3= length 

(2x-3)(x)=14
2x^2-3x=14 
2x^2-3x-14=0 
(2x- 7)(x+2)=0 
x=7/2 or x=-2

Since we know that negative values cannot exist in distance, we have to take 7/2 to as the correct answer. 

The width would be 3.5 yards 
Length= 2(3.5)-3 
=4 yards 

3.5 x 4 yards is the dimension of the rectangle 

Hope I helped :)

Macs farm has a total of 18 horses and 27 cows. what is the ratio of horses to cows in simplest form?
Evgesh-ka [11]
The ratio is basically finding the quotient of two numbers. If you want to find the ratio of horses to cows, divide the number of horses to that of cows.

Ratio = 18/27

When expressing it to its simplest form, make sure it is reduced. 18 and 27 are both factors of 9. So,

Ratio = 9*2/9*3
Cancelling out 9, the ratio at its simplest form is: <em>2/3</em>

Ruden bought 6 new books for his collection, increasing his collection by 12%. How many books did he have before his purchase?
forsale [732]

Answer:

he had 44 books before he bought those 6

Step-by-step explanation:

If you multiply 6 times 2 it is 12, which means if you take away 12 from 100 that is 88. if you divided 88 by 2 (the same thing you did to the 6 to make it 12%) that would be 44.
