Check the picture. There are 2 interior common tangents, and 2 exterior common tangents which can be drawn.
Answer: 4
Answer:
Pretty Simple!
Now that you know about ratios and all that, this is pretty tame compared to the last problem.
Now, the problem is talking 2D(2 Dimensions)
The ratio is not going to work because it has only one parameter.
Thus, we need to square it!

Thus, we have your correct ratio.
Now, we only need to do the same thing for the triangle problem. Meaning that, we need to compare the ratios, with x as the thing we are looking for.

See? X is practically handed to us.
Hope this helps!
Answer:
-50x
Step-by-step explanation:
-6x times 9 which is -54x
-54x-3x = -57x
-54x+7
Answer: 42.6% or you can round it to 43%
Step-by-step explanation:
first
second
and fifth are true
Basically the square root of -1 is i. From that you should be able to deduce the answers.
