Answer:
Step-by-step explanation:
the minimum of f is for x = 1 and f(1)=0
f is decreasing for x<=1 and increasing for x>=1
so the domain is 
x>=1 so x is positive and we can take the square root
so 
You just multiply 450 by .18 and it'll give you the 18% you have to add to 450.
So the equation would look like:
450(.18)=81
Which you then add:
450+81= 531
So 531 is your total!

The andwer would be 136 beause you would have to multiply 9 and 10 to get its area in square feet, then you would have to add the answer to that problem(90) to 46 square feet, and your answer would be 136
3x + 3 - x + 4 = 21
3x - x = 2x
2x +3 +4 = 21
3 + 4 = 7
2x + 7 = 21
-7 -7
2x = 14
