Answer:
10-3+7 9-2+7
Step-by-step explanation:
logic this is brain needs
If we want to compute 
, we have to substitute every occurrence of 
with 
in the definition of the function:
Similarly, computing 
means to substitute the input with 2:
So, we have
And finally
1. A rational number is a number that can be written as a fraction.
For example: 1/3, 5/7, 90/666, etc
Note: Any integer can be written as a fraction.
Look:
5 = 5/1 = rational
-14 = -14/1 = rational
2. There is no difference between a rational and integer.

Step-by-step explanation:
hope it helps you that is all I could do.
Answer:
8 / sqrt(3)
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp / adj
tan A = BC / AC
tan 30 = BC / 8
8 tan 30 = BC
8 * sqrt(3)/3 = BC
8/3 sqrt(3) = BC
