A! IM FREAKING OUT I NEED HELP NOW AND I WILL MARK BRAINLEST Question : What is the length of the common tangent between two non-intersecting circles with radii r and 3r, having the shortest distance between them equal to the radius of the first circle?

Given two circles, of given radii, have there centres a given distance apart, such that the circles don’t touch each other. The task is to find the length of the direct common tangent between the circles.

Step-by-step explanation:i had the same question

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
