The x-axis is the perpendicular bisector of the line segment joining the points (2,9) and (x, y). Find (x, y).

(2,-9).

Step-by-step explanation:

It is given that the x-axis is the perpendicular bisector of the line segment joining the points (2,9) and (x,y).

It means x-axis is the line of reflection and (x,y) is the image of (2,9) across the x-axis.

Rule of reflection is

The point (2,-9) is the mirror image of (2,9) across the x-axis.

Therefore, the point (x,y) is (2,-9).

the dimensions are:

step-by-step explanation:

we want to find the dimensions of a rectangular box with volume of

we factor to obtain;

we rewrite the rightmost factor to obtain;

recall that:

we apply difference of two squares formula to obtain;

hence the dimensions are

1/2*qr*rs
