Answer:
Step-by-step explanation:
Given :
To find : 9x^2 + 1 / 4 x^2
= > 2x - x / 3 = y
= > ( 6x - x ) / 3 = y
= > 5x / 3 = y
= > x = 3y / 5
Thus,
= > 9x^2 + ( 1 / 4 )x^2
= > x^2( 9 + 1 / 4 )
= > x^2{ ( 36 + 1 ) / 4 }
= > x^2 ( 37 / 4 )
Hence,
the value of 9 X square + 1 / 4 x square in terms of Y is equals to 3.33 y^2.
