If AC = CD, then each is half of AD, so each has length 12/2 = 6.

If AB = BC, then each is half of AC, so each has length 6/2 = 3.

The lengths are:

... AB = 3

... AC = 6

... AD = 12

... BC = 3

... BD = 9

... CD = 6

Since we have just listed the lengths of "all segments in the diagram," we presume that is the list from which our random segment is chosen. Of these 6 segments listed, 4 are longer than 3. The probability of interest is ...

... 4/6 = 2/3

_____

If you consider the segments in the diagram to be only AB, BC, and CD, then your probability is 1/3, since only CD is longer than 3.

What are the roots of the equation? x^2+24=14×

defon

$\begin{gathered} x^2+24=14x \\ x^2-14x+24=0 \end{gathered}$

Therefore,

$\begin{gathered} x^2-14x+24=0 \\ x^2-2x-12x+24=0 \\ x(x-2)-12(x-2)=0 \\ (x-2)(x-12)=0 \\ x=2 \\ or\text{ } \\ x=12 \end{gathered}$

(5,9), (5-3)<br> what is the slope?

Answer:

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

When you want to find out what the slope is, you have to remember what the formula is first....

$m=\frac{y}{x} =\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

so in this case -3 would be the $y_{2}$ because it's the y in the ordered pair and it's the second one. Then one of the 5's would be $x_{2}$ and 9 would be $y_{1}$ and then the other 5 would be $x_{1}$ .
