Answer:

4 - \sqrt{6}

Step-by-step explanation:

Rationalise the denominator by multiplying the numerator and denominator by the conjugate of the denominator.

the conjugate of 4 + \sqrt{6} is 4 - \sqrt{6} , then

= \frac{10(4-\sqrt{6}) }{(4+\sqrt{6})(4-\sqrt{6})  } ← expand denominator using FOIL

= \frac{40-10\sqrt{6} }{16-6}

= \frac{40-10\sqrt{6} }{10} ( divide terms on numerator/ denominator by 10 )

= 4 - \sqrt{6}

A 20-foot flagpole casts a 6-foot Shadow how tall is a nearby building that casts a 30-foot shadow
Viefleur [7K]

The building would be 100ft tall. You have to take 20/6 = ?/30 The difference between 6 and 30 is x5. Then all you have to do is 20x5 and you get 100ft.
