Answer:
158 natural numbers
158 natural numbers from 78 to 234, and 699 whole numbers from 24 to 721. Step-by-step explanation: Natural numbers are positive integers (whole numbers), so all numbers from the range of 78 to 234 would be included, including 78 and 234 itself.
Hope this helps, have a wonderful day/night, stay safe, happy holidays, and merry christmas!
 
        
                    
             
        
        
        
Answer:
The roots of the equation are x = 
 and x = 
and there are no real roots of the equation given above
Step-by-step explanation:
To solve:
5x² − 3x + 17 = 9
or
⇒ 5x² − 3x + 17 - 9 = 0
or
⇒ 5x² − 3x + 8 = 0
Now,
the roots of the equation in the form ax² + bx + c = 0 is given as:
x = 
in the above given equation
a = 5
b = -3
c = 8
therefore,
x = 
or
x = 
or
x = 
 and x = 
or
x = 
 and x = 
here i = √(-1)
Hence,
The roots of the equation are x = 
 and x = 
and there are no real roots of the equation given above
