Answer:
4230.14
Step-by-step explanation:
2040/1700=1.2
2448x1.2=2937.6
2937.6x1.2=3525.12
3525.12x1.2=4230.144
round to the nearest hundredth
4230.14
brainliest please
The answer is b thank you
Remember you can do anything to an equation as long as you do it to both sides
5c+16.5=13.5+10c
minus 5c both sides
16.5=13.5+5c
minus 13.5 from both sides
3=5c
divide both sides by 5
3/5=c
-30 is the answer
-6+4(-6)
-6+(-24)
-30
Answer:
(a) 
(b) Domain:
<em>(See attachment for graph)</em>
(c) 
Step-by-step explanation:
Given



Solving (a): A function; l in terms of w
All we need to do is make l the subject in 
Divide through by 2

Subtract w from both sides


Reorder

Solving (b): The graph
In (a), we have:

Since l and w are the dimensions of the fence, they can't be less than 1
So, the domain of the function can be

Solving (c): Write l as a function 
In (a), we have:

Writing l as a function, we have:

Substitute
for l in 
becomes
