Answer: the square root of 3 is: (a number) times ITSELF is equal to 3. Therefore, if you multiply that number times that number again, it is equal to 3.

Ex1- sqrt of 4 times the sqrt of 4 —> 2 times 2 which is 4

Ex2- sqrt of 9 times the sqrt of 9 —> 3 times 3 which is 9

The coordinates of the vertices of quadrilateral ABCD are A(-5, 1), B(-2,5), C(5, 3),

sladkih [1.3K]

Step-by-step explanation:

To calculate a slope, we need to apply: $m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

Applying formula to each slope:

$m_{AB}=\frac{5-1}{-2-(-5)} = \frac{4}{3} \\m_{BC}=\frac{3-5}{5-(-2)} =\frac{-2}{7}\\m_{CD}=\frac{-1-3}{2-5}=\frac{-4}{-3} =\frac{4}{3}$

So, as you can see, there are equal pair of slopes, meaning that they are parallels, which<em> demonstrate that it's actually a quadrilateral figure.</em>
