Answer:
1+1=3, See explenation
Step-by-step explanation:
1+1=2 but thats basically 2.1 because whole numbers are boring, but 2.1 is basically 2.2 because we want it as an even number, but 2.2 is basically 2.3 because 2.3 is the luckiest number, which is basically 2.5 if you think about it because 2.3 looks like 2/3 and two thirds can't be a whole (which is why we say 3/3 instead of 2/3) and 2.5 rounded up is 3. So thats how 1+1=3
To solve this problem you must apply the proccedure shown below:
1. You have the following points given in the problem above:

2. To find the midpoint, you must apply the formula that is used for calculate it. This is:

Where:

3. Now, you must substitute these values into the formula for calculate the midpoint, as following:

Therefore, the answer is: 
Answer:
Step-by-step explanation:
If the coordinates are (0, a) and (b, 0), we just use the distance formula to find the distance in terms of a and b:
and
which simplifies to

and that's it!
Answer:
x = 9.6
Step-by-step explanation:
Since point C is on line segment RB.
Therefore,
RC + CB = RB
2x + 9 + 3x - 12 = 45
5x - 3 = 45
5x = 45 + 3
5x = 48
x = 48/5
x = 9.6
