Question

1) Calcule os Polinômios:
a) (2x + 3y) + (5x + 4y)
b) (2x - 3y) + (5x + 4y) =
c) (4x + 3y) - (x + 4y)
d) (2x + y) + (5x + y) =

Se poderem ajudar me ajudaria muito:)​

Answer 1

Resposta:

a) 7x + 7y

b) 7x + y

c) 3x - y

d) 7x + 2y

Explicação passo-a-passo:

a) (2x + 3y) + (5x + 4y) =

2x + 3y + 5x + 4y =

2x + 5x + 3y + 4y =

7x + 7y

b) (2x - 3y) + (5x + 4y) =

2x - 3y + 5x + 4y =

2x + 5x - 3y + 4y =

7x + y

c) (4x + 3y) - (x + 4y) =

4x + 3y - x - 4y =

4x - x + 3y - 4y =

3x - y

d) (2x + y) + (5x + y) =

2x + y + 5x + y =

2x + 5x + y + y =

7x + 2y
