Answer:
100
Step-by-step explanation:
To make a perfect square trinomial, you want to divide the use the following equation to find the missing constant:
 when the quadratic is in standard form.
 when the quadratic is in standard form.
In this case, we would divide -20 by 2 and square it
-20/2 = -10
(-10)^2 = 100
 
        
                    
             
        
        
        
Answer:
Answer: Proved: the difference between squares of consecutive even numbers is always a multiple of 4. ... From the results above, we can see that 12, 20, and 28 are multiples of 4. Therefore, the difference between squares of consecutive even numbers is always a multiple of 4.

Answer:
The average rate of change in that interval is 1.99
Step-by-step explanation:
Here we have that the difference quotient for g(x) is:

Remember that for a general function f(x), the difference quotient is:

So if we look at the difference quotient for g(x), we can conclude that:

Also remember that the average rate of change in an interval (a, b) is just:

So here we want the average rate of change of g(x) in the interval from x = -2 to x = 1, this is:

The average rate of change in that interval is 1.99
