Midpoint is the middle segment of a given line. Since md = cm = 2 hence the point m is the midpoint of cd
A line is a distance between two points. Given the line cd with "m" as the midpoint, the distance between cm and md will be equal that is:
md = cm
Given the following parameters
md = 6x - 22cm = 3x - 10
Equate both expressions
6x - 22 = 3x - 106x - 3x = -10 + 223x = 12
x = 4
subtitute
cm = 3x - 10cm = 3(4) - 10cm =
Similarly:
md = 6x -22
md = 6(4) --22md =
Since md = cm = 2 hence the point m is the midpoint of cd

Answer:
Step-by-step explanation:
The question is a bit ambiguous. I believe that you are not adding 6 to 3 to get nine.
The only other choice would be 3*3 = 9
So a should 9 * 3 = 27
15 multiplied by 3 = 45
90 divided by 3 = 30
36 * 3 = 108
