Question

Please what is the answer?

Answer 1

When we have a set of points, we can find the distance between them using the formula:

`d=\sqrt{(x_(2)-x_(1))^2+(y_(2)-y_(1))^2 }`, where d is the distance, x1 and x2 are one point and y1 and y2 are another point.

OB:

Thus, for OB, we can allow O(6, 6) to be our x1 and x2 point and we can allow B(9, 6) to be our y1 and y2 point:

`d=√((6-9)^2+(6-6)^2) \\d=√((-3)^2+(0)^2) \\d=√((-9)) \\d=3`

Thus, the first part/step in the equation is your subtraction expression to find the length of OB.

AB:

For AB, we can allow A(9, 10) to be our x1 and x2 point and we can allow B (9, 6) to be our y1 and y2 point:

`d=√((9-9)^2+(10-6)^2)\\ d=√((0)^2+(4)^2)\\ d=√(16)\\ d=4`

The first part/step is your subtraction expression for the length of AB.
