Answer 2

Finding the Distance between Points A and B

To find the distance between points A and B on the coordinate plane, we can use the distance formula. The distance formula is derived from the Pythagorean theorem and calculates the distance between two points (x1, y1) and (x2, y2) as follows:

Distance = √((x2 - x1)^2 + (y2 - y1)^2)

In this case, point A is represented as (x + 3) and point B is represented as (x - 1). Let's substitute these values into the distance formula and calculate the distance between points A and B.

Distance between A and B = √((x - 1 - (x + 3))^2 + (y - y)^2)

Simplifying the equation:

Distance between A and B = √((-4)^2 + 0^2) = √(16 + 0) = √16 = 4

Therefore, the distance between points A and B is 4 units.

Finding the Distance between Points A and C

To find the distance between points A and C, we need to know the coordinates of point C. However, the given information only provides the expression (2x + 5) for point C, without specific coordinates. Without the specific coordinates of point C, we cannot calculate the distance between points A and C.

If you have the specific coordinates of point C, please provide them, and I will be happy to help you calculate the distance between points A and C.
