Answer 1

Answer:

10 6 16 12 ok ok ok ok ok ok ok it is wrong

Answer 2

Step-by-step explanation:

$7. \: solve : \\ \frac{(x + 1)(x + 9)}{(x + 2)(x + 4)} = \frac{(x + 6)(x + 10)}{(x + 5)(x + 7)} \\ \frac{x ( x+ 9)+ 1(x + 9)}{x (x + 4)+ 2(x + 4)} = \frac{x(x + 10) + 6(x + 10)}{x (x + 7)+ 5(x + 7)} \\ \frac{{x}^{2} + 9x + x + 9}{ {x}^{2} + 4x + 2x + 8 } = \frac{ {x}^{2} + 10x + 6x + 60 }{ {x}^{2} + 7x + 5x + 35} \\ \frac{{x}^{2} + 10x + 9}{ {x}^{2} + 6x + 8 } = \frac{ {x}^{2} + 16x + 60 }{ {x}^{2} + 12x + 35}$
