Answer:
the factors of  f(x)=x^3+8x^2+5x-50 are (x-2)(x+5)(x+5)
Step-by-step explanation:
We need to factorise the function 
If a number is a factor of this function than it must be completely divisible by last co-efficient. Our last co-efficient is -50
Checking few numbers:

So, f(2)=0 which means x-2 is a factor of the given function. Now we will perform long division of  by (x-2) to find other factors
 by (x-2) to find other factors
The long division is shown in figure attached.
After long division we get: 
The equation  can be further simplified as: (x+5)(x+5) or (x+5)^2
 can be further simplified as: (x+5)(x+5) or (x+5)^2
So, the factors of  f(x)=x^3+8x^2+5x-50 are (x-2)(x+5)(x+5)
 
        
             
        
        
        
1 mile is 5,280 ft, and 1 second has 1,000,000 microseconds.
So 186,000 miles per second multiplied by 5,280 feet per mile gives 982,080,000 feet per second.
Dividing this value by 1,000,000 microseconds per second gives the final answer of 982.08 feet per microsecond.
        
             
        
        
        
 Answer:
The first two is x=60
Step-by-step explanation:
1.5/90 = 1/x
1.5x = 90 x 1
1.5x/1.5 = 90/1.5
x = 60
 
        
                    
             
        
        
        
Answer:
4,782,969
Step-by-step explanation:
9^7 
Written in expanded form = 9 times 9 times 9 times 9 times 9 times 9 times 9 
= 9 × 9 × 9 × 9 × 9 × 9 × 9
= 4,782,969
9^7 means multiplying 9 in 7 places
9^7 = 4,782,969
