30x-40+12=572
30x=600
x=20
(4,12)(5,15)
slope = (15 - 12) / (5 - 4) = 3/1 = 3....so the slope is 3
y = 3x...slope here is 3 as well
they have the same slope
You cannot find the area of parallelogram ABCD without providing information or any numbers of units. It is therefore impossible to solve without further information or an image.
Answer:

So then the best option would be:
a. 1/25
Step-by-step explanation:
For this case we assume that the sample space for the numbers is :
![S_1= [A,B,C,D,E]](https://tex.z-dn.net/?f=%20S_1%3D%20%5BA%2CB%2CC%2CD%2CE%5D)
And the sample space for the numbers is:
![S_2 =[1,2,3,4,5]](https://tex.z-dn.net/?f=%20S_2%20%3D%5B1%2C2%2C3%2C4%2C5%5D)
Both sampling spaces with a size of 5.
We define the following events:
A="We select a 2 from the numbers"
B= "We select a E from the letters"
We can find the individual probabilities for each event like this:


And assuming independence we can find the probability required like this:

The last probability is the probability of obtain obtain a 2 AND an E
So then the best option would be:
a. 1/25
