Answer:
Logically, the answer is either 12 or 42 
 
        
             
        
        
        
Formula for perimeter of a rectangle = 2(L + W)
let the number be x
width = 2x + 8
length = 3(2x + 8)
substitute respectively 
96 = 2 (2x + 8 + 3(2x + 8)) open the bracket 
96 = 2 ( 2x + 8 + 6x + 24) collect like terms
96 = 2 (8x + 32) open the bracket
96 = 16x + 64
collect like terms
96 - 64 = 16x
32 = 16x
divide both sides by 16
32/16 = 16x/16
2 = x
therefore, the width = 2x + 8 = 2(2) + 8 = 4 + 8 = 12.
and the length = 3(2x + 8) = 6x + 24 = 6(2) + 24 = 12 + 24 = 36.
        
             
        
        
        
<span>The graph you plotted is the graph of f ' (x) and NOT f(x) itself. </span>
Draw a number line. On the number line plot x = 3 and x = 4. These values make f ' (x) equal to zero. Pick a value to the left of x = 3, say x = 0. Plug in x = 0 into the derivative function to get
f ' (x) = (x-4)(6-2x)
f ' (0) = (0-4)(6-2*0)
f ' (0) = -24
So the function is decreasing on the interval to the left of x = 3. Now plug in a value between 3 and 4, say x = 3.5
<span>f ' (x) = (x-4)(6-2x)
</span><span>f ' (3.5) = (3.5-4)(6-2*3.5)
</span>f ' (3.5) = 0.5
The function is increasing on the interval 3 < x < 4. The junction where it changes from decreasing to increasing is at x = 3. This is where the min happens.
So the final answer is C) 3
        
             
        
        
        
Answer:
 is the number of quarters and
 is the number of quarters and  is the number of dimes
 is the number of dimes
Step-by-step explanation:
we know that


Let 
x-----> the number of dimes
y------> the number of quarters
we know that
 -----> equation A
 -----> equation A
 ----Isolate the variable y
 ----Isolate the variable y
 -----> equation B
 -----> equation B
Substitute equation B in equation A
 
       
 
 
 
 
 
 
 
 
Find the value of y


therefore
 is the number of quarters and
 is the number of quarters and  is the number of dimes
 is the number of dimes
 
        
                    
             
        
        
        
Answer:
its Aor the first option because it has repeated x values making it not a function.
