You plug -2 in for the function k(p) and add it to the function g(w), getting 
(-2+3)*(-2-7)+(-2-5)^2=1*-9+49=40 for a - I challenge you to do B on your own!
        
             
        
        
        
Answer:
The correct answer is option C
(f o g)(x) = 3x² + 7x + 2
Step-by-step explanation:
<u>Points to remember</u>
<u>Composite functions</u>
Let f(x) and g(x) be the two functions then (f o g)(x) can be written as
(f o g)(x) = f(g(x))
<u>To find the value of (f o g)(x)</u>
Here f(x) =x + 2  and g(x) = 3x² + 7x
(f o g)(x) = f(g(x))
  = f(3x² + 7x)
  = 3x² + 7x + 2
Therefore the correct answer is option C
(f o g)(x) = 3x² + 7x + 2

Answer:
- 26 ounces of 55% solution
 - 104 ounces of 80% solution
 
Step-by-step explanation:
Let x represent the quantity of 80% solution. Then 130-x is the amount of 55% solution. The total amount of salt in the mix is ...
   0.80x +0.55(130 -x) = 0.75·130
   0.25x = 0.20·130 . . . . . . . subtract 0.55(130)
   x = 0.20/0.25(130) = 104
   130-x = 26
She should use 26 ounces of 55% solution and 104 ounces of 80% solution.
