Go step by step to reduce the radical. V108 VOVO try You must answer all questions above in order to submit.
katen-ka-za [31]

To reduce the radical, you have to factorize 108.

108 is a multiple of 3, so to factorize it, you can divide it by 3

\frac{108}{3}=36

You can rewrite the square root as:

\sqrt[]{3\cdot36}=\sqrt[]{3}\cdot\sqrt[]{36}

The square root of 36 is equal to 6 so you can write the expression as:

\sqrt[]{3}\cdot\sqrt[]{36}=6\sqrt[]{3}

AB and BC form a right angle at their point of intersection. This means AB is perpendicular to BC.

We are given the coordinates of points A and B, using which we can find the equation of the line for AB.

Slope of AB will be:

m= \frac{-1-1}{14-2}=-1/6

Using this slope and the point (2,1) we can write the equation for AB as:

y-1= \frac{-1}{6}(x-2) \\  \\ &#10;y= -\frac{1}{6}x+ \frac{1}{3}+1 \\  \\ &#10;y=-\frac{1}{6}x+ \frac{4}{3} &#10;

The above equation is in slope intercept form. Thus the y-intercept of AB is 4/3.

Slope of AB is -1/6, so slope of BC would be 6. Using the slope 6 and coordinates of the point B, we can write the equation of BC as:

y - 1 = 6(x - 2)
y = 6x - 12 + 1
y = 6x - 11

Point C lies on the line  y = 6x - 11. So if the y-coordinate of C is 13, we can write:

13 = 6x - 11
24 = 6x
x = 4

The x-coordinate of point C will be 4.

Therefore, the answers in correct order are:

4/3 ,  6,  -11,  4
