Answer 1

Resposta:

1) Faça o agrupamento dos monômios abaixo:

a) – 4a + 10a = 6a

b) 15x – 20x = -5x

c) -2x + 4x = 2x

d) – 4x – 5x -10x = -19x

e) 3ax + 5bx – 12 ax – 15 bx

= 3ax - 12ax + 5bx - 15bx

= -9ax - 10bx

f) 15y – 4z + 3x + 12y – 20z

= 15y + 12y - 4z - 20z + 3x

= 27y - 24z + 3x

g) -5y -12x + 10x + 9y

= -5y + 9y - 12x + 10x

= 4x - 2x

h) x + 2x + 5x = 8x
