Question

Aplique a propriedade distributiva:
a)2.(3a+4m)
b)3.(a+2m)
c)7.(3x+y)
d)a.(x-y)
e)4.(2a-x)
f)7.(x-y)
g)-7.(x-y)
h)3.(2x+y)
i)-3.(2x+y)
j)2.(3a-4y)
k)-2.(3a-4y)

Answer 1

Explicação passo-a-passo:

a) 2.(3a + 4m) = 6a + 8m

b) 3.(a + 2m) = 3a + 6m

c) 7.(3x + y) = 21x + 7y

d) a.(x - y) = ax - ay

e) 4.(2a - x) = 8a - 4x

f) 7.(x - y) = 7x - 7y

g) -7.(x - y) = -7x + 7y

h) 3.(2x + y) = 6x + 3y

i) -3.(2x + y) = -6x - 3y

j) 2.(3a - 4y) = 6a - 8y

k) -2.(3a - 4y) = -6a + 8y
