Question

Please help!!! Thank you!!

Answer 1

The distance from Q to R is 12 units.

Step-by-step explanation:

Given points are:

Q(-4,6) and R(8,6)

$x_1=-4, \ \ \ \ \ \ y_1=6\\x_2=8, \ \ \ \ \ \ y_2=6$

Using point distance formula;

$Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\\\Distance=\sqrt{(8-(-4))^2+(6-6)^2}\\\\Distance=\sqrt{(8+4)^2+(0)^2}\\\\Distance=\sqrt{(12)^2+0}\\\\Distance=\sqrt{144}\\\\Distance=12\ units$

The distance from Q to R is 12 units.
