Question

(2x + 3y)2 + (6x - 5y)?​

Answer 1

Step-by-step explanation:

(2x + 3y)2 + (6x - 5y ) =

2 × (2x + 3y ) + (6x - 5y)=

4x + 6y + 6x - 5y =

(4x + 6x ) + ( 6y - 5y )=

10x + y ( Answer)

Answer 2

${\tt{\purple{\underline{\underline{\huge{Answer:}}}}}}$

-5y = 12 -5y/-5 = 12/-5 y= -12/5 (3, -12/5) Put the value of y = -2, 6x – 5(-2) = 30 ... 2x + 3y = 12. Put the value of x = 0 2 × 0 + 3y = 12 3y = 12 3y/3 = 12/3 y = 4
