Final answer:
The distance between points A (4,0) and B (8,0) is 4 units.
Step-by-step explanation:
The distance between two points in a coordinate plane can be found using the distance formula: d = sqrt((x2 - x1)^2 + (y2 - y1)^2).
In this case, the coordinates of point A are (4,0) and the coordinates of point B are (8,0). Plugging these values into the distance formula, we get:
d = sqrt((8 - 4)^2 + (0 - 0)^2) = sqrt(4^2 + 0^2) = sqrt(16 + 0) = sqrt(16) = 4.
Therefore, the distance between points A and B is 4 units.
