Answer:
D.−√5
Step-by-step explanation:
4 sqrt(20) -3 sqrt(45)
We know that sqrt(ab) = sqrt(a) sqrt(b)
4 sqrt(4) sqrt(5) - 3 sqrt(9) sqrt(5)
4 *2 sqrt(5) - 3 *3 sqrt(5)
8 sqrt(5) - 9 sqrt(5)
- sqrt(5)
 
        
             
        
        
        
Answer:
46,000,000 (46 million)
Step-by-step explanation:
If the number to the right (in this case the hundred thousands place) is 5 or greater then you round up. 
If it was lower than 5 you would round down.
As the number in the hundred thousands place is 6, this means we can round up.
 
        
                    
             
        
        
        
Answer:
<h2>f(x) = 4</h2>
Step-by-step explanation:
f(x) = 2x
When x = 2
Substitute the value of x into f(x)
That's
f(2) = 2(2)
= 4
