Answer 2

Координата середины отрезка равна полусумме соответствующих координат, т.е

Если середина AB -  O ,то    O(12:2+18:2)=O(15)

Ответ: O(15)

Answer 3

Calculating the Midpoint of Line Segment AB

To find the midpoint of the line segment AB with endpoints A(12) and B(18), we can use the midpoint formula, which states that the coordinates of the midpoint M(x, y) of a line segment with endpoints A(x1, y1) and B(x2, y2) are given by:

Midpoint Formula: M(x, y) = ((x1 + x2) / 2, (y1 + y2) / 2)

Applying the Midpoint Formula

Using the given coordinates A(12) and B(18), we can apply the midpoint formula to find the coordinates of the midpoint M.

Given: A(12) B(18)

Midpoint Formula: M(x, y) = ((x1 + x2) / 2, (y1 + y2) / 2)

Calculation: x = (12 + 18) / 2 y = (12 + 18) / 2

Result: The coordinates of the midpoint M are (15, 15).

Conclusion

The coordinates of the midpoint of the line segment AB, with endpoints A(12) and B(18), are (15, 15).
