Answer 1

Resposta:

a]7x-2y dclp só sei essa

Answer 2

Oie, Td Bom?!

a)

$= 2x + 4y + 5x - 6y$

$= 7x + 4y - 6y$

$= 7x - 2y$

b)

$= 13x - 5x$

$= 8x$

c)

$= (3x) \: . \: (4x {}^{2} )$

$= 3x \: . \: 4x {}^{2}$

$= 12x {}^{3}$

d)

$= 27x {}^{3} \div 3x$

$= 9x {}^{2}$

e)

$= 9x - 3x {}^{2} + 7x + 12x {}^{2}$

$= 16x - 3x {}^{2} + 12x {}^{2}$

$= 16x + 9x {}^{2}$
