Answer:
46
Step-by-step explanation:
Since B is the midpoint of AC, the segments AB and BC must have equal length. This means that x + 13 = 2x + 3. Solving this, we see that x = 10. By substituting 10 for x, we see that the length of AB is 23, so the length of AC is 2*23, which is 46.
It will says divided by or took away for subtracting and put in for adding
The answer would be multiplies by 1/3
Pythagoras:
sqrt( 9^2+12^2) = sqrt( 81+144) = sqrt(225) = 15! Voila :)
5,392,029,004 is how you write it.
