The probability that a point is chosen at random in the square is in the blue region is 0.8.
<h3>What is Probability?</h3>
The probability helps us to know the chances of an event occurring.

As we know that the area of the shaded region is the sum of the area of triangle A and the area of triangle B. Therefore, the area of the blue shaded region is,


The area of the square can be written as,

Now, the probability that a point is chosen at random in the square is in the blue region can be written as,


Hence, the probability that a point is chosen at random in the square is in the blue region is 0.8.

For the first equation, to get an equation that only has 1 solution your two missing numbers could be 3x and 6. This is because when you solve it, you get 7x + 2 = 3x + 6
- 3x
4x + 2 = 6
- 2
4x = 4
x = 1
For the second equation, your two numbers could be 7x and 4, because it means that x has to be different as 7 multiplied by one number and added to 2 cannot equal 7 multiplied by the same number but added to 4.
I hope this helps!
Have you learnt about prime numbers yet? 5 is a prime number so you can't break it up into smaller numbers other than obviously 5*1. 39 is not a prime number. At first glance you should be able to tell that its a multiple of 3 right?
39=3*13
Now you have smaller numbers.
3*13*5=13*15.
I guess that's what the answer is.
