Step-by-step explanation:
9^2-6^2=c^2
81-36=c^2
45=c^2
c=sqrt(45)
 
        
                    
             
        
        
        
take your compass on a point on your line. then draw a circle. take the 2 points in which the circle hit the line and draw 2 circles larger than half the distance between he 2 points. take the point that they intersect and and connect it to the line and you point M and it is purpendicular. does that make sense?
 
        
             
        
        
        
Answer:
Step-by-step explanation:
<u>Simplify the numerator:</u>
- 1/x² + 2/y = 
- y/(x²y) + 2x²/(x²y) =
- (2x² + y)/(x²y)
<u>Simplify the denominator:</u>
- 5/x - 6/y² = 
- 5y²/(xy²) - 6x/(xy²) = 
- (5y² - 6x) / (xy²)
<u>Simplify the fraction:</u>
- (2x² + y)/(x²y) ÷ (5y² - 6x) / (xy²) = 
- (2x² + y)/(x²y) × xy² / (5y² - 6x) =
- y(2x² + y) / x(5y² - 6x)
