Answer 1

Explicação passo-a-passo:

a) 8a + 2a = 10a

b) 7x - 5x = 2x

c) 2y² - 9y² = -7y²

d) 4a² - a² = 3a²

e) 4y - 6y = -2y

f) -3m² + 8m² = 5m²

g) 6xy² - 8y²x = -2xy²

h) 5a - 5a = 0

2)

a)

7x - 5x + 3x

= 2x + 3x

= 5x

b)

2y - y - 10y

= y - 10y

= -9y

c)

4a + a - 7a

= 5a - 7a

= -2a

d)

ab - ab + 5ab = 5ab

e)

4x³ - x³ + 2x³

= 3x³ + 2x³

= 5x³

f)

10x - 13x - x

= -3x - x

= -4x

g)

8x - 10x + 4x

= -2x + 4x

= 2x
