Answer 1

Resposta:

Explicação passo-a-passo:

Boa noite!

a) 7ry – 3ry =  

= 4ry

b) 20ab – 3ab – 8ab =

=  20ab – 11ab =

= 9ab

c) 7r² – 3r² – 4r² =

= 7r² – 7r² =

=  0

d) 4a – 3a =

= a

e) 3ax + 12 ax – 15 ax =

= 15ax – 15 ax =

= 0

f) 15y – 4z + 3x + 12y – 20z =

=  3x + 15y + 12y– 4z – 20z =

= 3x + 27y – 24z

g) 24aw + 6x – 12aw – 6x =

= 24aw – 12aw + 6x  – 6x =

= 12aw

h) 15ax + 6ax =

= 21ax

i) by + 15by =

= 16by

j) 32cz ³- 24cz ³ =

= 8cz ³
