Find the equation of pair of lines represented by the equation x2-5xy+4y2=0

tried my best!

Step-by-step explanation:

We have a = 1, h = −5/2 and b = 6. Also h2 = 25/4 > 6 = ab. Therefore, x2− 5xy + 6y2 = 0 represents a  pair of lines passing through origin. Further,  x2− 5xy = 6y2 = (x− 2y)(x− 3y)  The lines are x − 2y = 0 and x − 3y = 0.Read more on Sarthaks.com - https://www.sarthaks.com/502122/find-the-lines-represented-by-the-equation-x-2-5xy-6y-2-0?show=502131#a502131

the dimensions are:

step-by-step explanation:

we want to find the dimensions of a rectangular box with volume of

we factor to obtain;

we rewrite the rightmost factor to obtain;

recall that:

we apply difference of two squares formula to obtain;

hence the dimensions are

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you
