Answer:
X=-6
Step-by-step explanation:
Well first off, you need to add 25.50+15.30+9.25 which equals 50.05 then you would subtract that from 72 so 72-50.5 which gets your answer of 21.95 centimeters
The first (and most typical) way to find distance of two points is by using the distance formula.

One alternative is the Manhattan metric, also called the taxicab metric. This option is much more complicated, and rarely used in high school math. d(x,y)=∑i|xi-yi|
Trick question. For the reflections given in the problem statement, the x-coordinate doesn't change. The number that goes in the green box is 1.
Answer:
30:16-15:8 That is simplified and I divided it by two.
