Question

x : y = 9:18, find the value of ( 2x² + 3y²): (2x² - 3y²).​

Answer 1

Answer:

Given

x/y =9/18 = 1/2

Therefore y=2x

To find : -  ( 2x² + 3y²)/(2x² - 3y²).​

Solution :- Put y =2x

( 2x² + 3y²)/(2x² - 3y²) = ( 2x² + 12 x²)/(2x² -12 x² )

                                     = 14x²/ -10 x²

                                    =  -7/5 or -7: 5

Answer 2

Step-by-step explanation:

x=9z,y=18z

2.9z^2+3.18z^2:2.9z^2-3.18z^2

18z^2+54z^2:18z^2-54z^2

72z^2:-46z^2

72/46=36/23

36z^2:23z^2
