5^2 is 25 and 25x6 is 150sq ft
        
                    
             
        
        
        
Answer:
7
Step-by-step explanation:
The average rate of change of f(x) in the close interval [ a, b ] is

Here [ a, b ] = [2, 5 ]
f(b) = f(5) = 2(5)² - 7(5) = 50 - 35 = 15
f(a) = f(2) = 2(2)² - 7(2) = 8 - 14 = - 6, thus
average rate of change =  =
 =  = 7
 = 7
 
        
             
        
        
        
There as 16 cards, 2 of which are wildlife cards, so the ratio is 16 : 2. We can simplify it by dividing both sides by 2, so we'll get the ratio of 8 : 1.
I hope this helps! :)
        
             
        
        
        
Answer:x = 7
Step-by-step explanation:
Similar figures have sides that are proportional.  Setting up a proportion for the sides of the figures will help solve for 'x':
Cross-multiply:  3(x + 1) = 6(x - 3)
Distribute:  3x + 3 = 6x - 18
Combine like terms:  21 = 3x
Solve for 'x':  x = 7
