What is the greatest common factor of 45, 50, 84?

the greatest common factor is B - 1

Step-by-step explanation:

not 5 because 85 doesn't end with 0 or 5

not 3 because 5+0 doesn't equal a multiple of 3

not 2 because 45 is odd

not 0 because that's never an answer

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6
