Answer:
- incorrect
- correct
- incorrect
Step-by-step explanation:
A + B = (-4x^2 +2x -5) +(3x^2 +6) = x^2(-4+3) +x(2) +(-5+6) = -x^2 +2x +1
   The given sum is Incorrect.
__
A - C = (-4x^2 +2x -5) -(-5x -4) = -4x^2 +x(2+5) +(-5+4) = -4x^2 +7x -1
    The given difference is Correct.
__
B + C = (3x^2 +6) +(-5x -4) = 3x^2 -6x +2
   The given sum is Incorrect.

Answer:
The length of the hypotenuse is 26 inches 
Step-by-step explanation:
The leg(brace) attached to the wall is 10 inches 
Perpendicular = 10 inches 
Your surfboard sits on a leg that is 24 inches.
Base = 24 inches 
Formula : 


Hypotenuse = 26 
Hence  the length of the hypotenuse is 26 inches 
 
        
             
        
        
        
The average rate of change, of the function, between the intervals, x = 2 to x = 6 is: 180.
<h3>What is the Average Rate of Change of a Function?</h3>
Average rate of change =  .
.
Given the function,  ,
,
The average rate of change using the intervals of, x = 2 to x = 6 would be solved as shown below:
a = 2
b = 6
f(a) =  = 34
 = 34
f(b) =  = 754
 = 754
Average rate of change = 
Average rate of change = 180
Therefore, the average rate of change, of the function, between the intervals, x = 2 to x = 6 is: 180.
