Answer:
9
Step-by-step explanation:
you can divide all three numbers by 9 and anything bigger than 9 wouldn't divide 9 to a whole
so the answer is 9
The factors of 9 are: 1, 3, 9
The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, 36
The factors of 189 are: 1, 3, 7, 9, 21, 27, 63, 189
Then the greatest common factor is 9.

(x - 6)(x + 3)
Given
x² - 6x + 3x - 18 ( factor the first/second and third/fourth terms )
= x(x - 6) + 3(x - 6) ← factor out (x - 6) from each term
= (x - 6)(x + 3)
7 2/3 minutes
We can write this equation in y = mx+b form
where m = 3 ft/min and b = -105 ft
x is the number of minutes and y is the depth
y = 3 * x -105
We want to find when y = -82
-82 = 3x -105
Add 105 to each side
-82+105 = 3x-105+105
23=3x
Divide by 3
23/3 = 3x/3
23/3=x
Changing into a mixed number
3 goes into 23 7 times with 2 left over
