Rationalize the denominator of the fraction and enter the new denominator below.<br><br>8/2-√12

Studentka2010 [4]

$\frac{8}{2-\sqrt{12}}=\frac{8}{2-\sqrt{4\cdot3}}=\frac{8}{2-2\sqrt3}=\frac{8}{2(1-\sqrt3)}=\frac{4}{1-\sqrt3}\\\\\frac{4}{1-\sqrt3}\cdot\frac{1+\sqrt3}{1+\sqrt3}=\frac{4(1+\sqrt3)}{1^2-(\sqrt3)^2}=\frac{4(1+\sqrt3)}{1-3}=\frac{4(1+\sqrt3)}{-2}=-2(1+\sqrt3)}\\\\=-2-2\sqrt3$

$if\ \frac{8}{2}-\sqrt{12}=4-\sqrt{4\cdot3}=4-2\sqrt3$

If each mark represents one unit, which number does A represent?<br> (the picture is down below :)

My name is Ann [436]

A represents 77 units
You take the only number given (75) and count the tick marks, adding one every time you go right, subtracting one every time you go left. Mark A is 2 tick marks to the right of 75, so you add 2 to 75, making 77 units
