Answer:
The interval notation for the domain is
.
Step-by-step explanation:
Consider the provided information.
It is given that 
We need to find the value of
.
Put the value of g(x) in
.
....(1)
Now, put x=x-7 in 



From equation 1.

The domain of the function is the set of input values for which a function is defined.
Here, the value of
should be greater or equal to 0 as the square root of a negative number is not real.
Domain= 
The value of x is all real number greater than
.
Hence, the interval notation for the domain is
.
Answer:
x=1

Answer:
.10
Step-by-step explanation:
Answer:
P = 20.
Step-by-step explanation:
Given that:
the variable that is not given is P. So to find out P, we substitute the two given values into the equation as following:
P= 2L + 2W
<=> P = 2(6) + 2(4)
<=> P = 12 + 8
<=> P = 20.
Hope it will find you well.
