Answer: 4 is 12 and 5 is 18

Step-by-step explanation: The midpoint of a line is the exact middle of the line. In other words, it splits the line into two equal parts.

From a formulaic standpoint, this looks like

AC = CB

And if we plug in the values it looks like this

AC = 12, so 12 = CB.

For the next problem,

AC + CB = AB

AC = 9, and since AC = CB, CB = 9 also.

So, once again just put the numbers in for the letters and you get

9 + 9 = 18
