Answer:
2√5 units ≈ 4.47 units (nearest hundredth)
Explanation:
To find the distance between point A and O(0, 0), we first need to find the coordinates of point A.
Given linear equations:

We are told that point A is the point of intersection of the two lines.
Therefore, to find the x-coordinate of point A, substitute the first equation into the second equation and solve for x:

Substitute the found value of x into the first equation and solve for y:

Therefore, the coordinates of A are (4, -2).
To find the distance between A(4, -2) and O(0, 0) we can use the distance formula.

Substitute the two points into the formula and solve for d:

Therefore, the distance between point A and O(0, 0) is 2√5 units, which is approximately 4.47 units (rounded to the nearest hundredth).
