The answer is 54 because you add them
To determine the length of AB, one must subtract BC from AC. If the length of AC is 18 and the length of BC is 4, then using this formula yields 18 - 4 = 14, so the length of AB is 14.
This postulate also allows a line segment that has only two known points to be broken into two line segments with the addition of a third point in between the endpoints. This is useful for proofs in geometry and analysis.
0.75 because 100cm = 1m so you just move the decimal to the right by 2
The square root of 75000 is 273.86
Sales tax is:
$62.80* (6/100)= $3.77
