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

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
