Answer:
Composition: 
Domain = {
}
Step-by-step explanation:
Given

The requested composition becomes:

Then the Domain consists of all Real x-values for which the function is defined. In this case, the function is defined for all x-values for which the square root is defined, that is all x values for which:
(so the square root is defined in the Real number system)
This means 
The Domain is then all the Real x-values such that 
Answer:
its the 2nd on on the top row
Step-by-step explanation:
"The length of a rectangle is 5/2 units greater than its width"
'greater' here means multiplication, 5/2 units greater or 5/2 times more. So we know that the length is

.
Perimeter of a rectangle is:

Plug in our value for the length:
