c) 8ab – 7ab – 5a – 6b=

Pra hojeeeeee plmds

Answer 1

Oie, Td Bom?!

a)

$= 12x + 15x - 22x + 15x$

$= (12 + 15 - 22 + 15)x$

$= (42 - 22)x$

$= 20x$

b)

$= 17a + 17x - 12x + 5a$

$= (17 + 5)a + (17 - 12)x$

$= 22a + 5x$

c)

$= 8ab - 7ab - 5a - 6b$

$= (8 - 7)ab - 5a - 6b$

$= 1ab - 5a - 6b$

$= ab - 5a - 6b$
