The correct answer to this question is that the cheetah can run 369,000
feet per hour. We can work this out in the following way:
 One mile equals 1760 yards
 In feet that is 3 x 1760 or 5,280
 So Feet per hour will be 5280 x 70 or
 369,600 feet per hour.
        
                    
             
        
        
        
Answer:
short story has 32 pgs
novel has 416 pgs
Step-by-step explanation:
a novel (N) has 13 times as many pages as a short story (x) so, N = 13X
total pages is the equation N + x = 448
plug the equation for N into this
13x + x = 448, combine like terms
14x = 448, divide both sides by 14
x = 32. so now we know that the short story has 32 pages. subtract that from 448. and the novel has 416 pages. 
 
        
             
        
        
        
Are you sure you've copied down the original problem exactly as given?  i38 = 38i can't be simplified.  Perhaps you meant i^38, which is a different matter.
Note that i^38 = i^32 * I^4 * I^2.
Note that i^0, i^4, i^8, etc., all equal 1.  Therefore,
i^38 = (1)(1)i^2 = 1*(-1) = -1 (answer)
        
                    
             
        
        
        
Answer: Unit rates are the factor that takes you from one column to the other column in a table of equivalent ratios. Equivalent ratios have the same unit rates.

Here the denominators are quadratics , so we need to factorise them first
1/(x²-5x) +3/(x²+2x-35)
factorising x²-5x , 
here GCF is x, so taking x out we have
x(x-5)
factorising x²+2x-35 using AC method,
we find factors of -35 that add up to give 2
(x-5)(x+7)
Since we have x-5 common in both denominators, so lcd of the rational expression will be product of x(x-5)(x+7) 
lcd is x(x-5)(x+7)
