Find the distance between the two points
(-2,-9) and (3,3).

7

Step-by-step explanation:

The distance formula is an algebraic expression used to determine the distance between two points with the coordinates (x1, y1) and (x2, y2).

D=√(x2−x1)^2+(y2−y1)^2

SUBSTITUTING

√(-9-(-2))^2 +(3-3)^2

√(-9+2)^2+0

√(-7)^2

√(49)

Ans is 7

If you are going from point (-2,-9) to (3,3) the distance is 12 units up and 5  units to the right . If you are going from point (3,3) to (-2,-9) it is 12 units down and 5 units to the left.

Step-by-step explanation:

First you plot the coordinates (-2,-9) and (3,3) on the coordinate plane grid or graph. Then you carefully count 5 units to the left or right (depends from which coordinate you are starting from) and then 12 units down or up.

I made sure I used a graph to ensure this is correct.

Hope this helps :)

AD = 19

Step-by-step explanation:

Here, we want to find the length of AD

To do this, we will use the illustration drawn below in the attachment

Since B is the midpoint of AC, and BC = 8; then AB will also be 8

Mathematically;

AD = AB + BD

AD = 8 + 11

AD = 19
