4 common tangents = circles do not touch
3 common tangents = circles touch at one point
2 common tangents = circles overlap1 common tangent = circles touch at one point and one is inside the other
0 common tangents = circles do not touch and one is inside the other
Refer to the image if you need to
-14a-5=-12
+5 +5
-14a=-7
Divide -7 by -14a
a=2
Only the division of two rational numbers might be irrational.

Answer: The expression would look like 2x+(25+3y).
Step-by-step explanation:
Let the number be x
2x+(25+3y)
There are 36 different combos for the two: 6 possibilities for the first die times 6 for the second.
Out of those 36, 10 have a sum of 9 or higher:
3&6, 4&6, 4&5, 5&4, 5&5, 5&6, 6&3, 6&4, 6&5, 6&6
The probability is 10/36, which reduced is 5/18.
As a decimal it is 0.2
and as a percent it is 27.
%.
Hope this helps!
