CAN SOMEONE TELL ME THE ANSWER PLEASE????????????????????????? Worth 20 points

Answer:
12
Step-by-step explanation:
Okay, so on a grid, points Q and R are parallel to each other on the point 6, we just have to figure out how far apart they are, and to figure that out, we have to find the distance between 8 and -4 so:
8 - -4 = 8 + 4 = 12
So, the distance from point Q to point R is 12
if this is wrong please let me know
hope this helps:)
