Question

5. Aplique a propriedade distributiva e
efetue quando possível.
a) 4. (3 + 5)
b) 2. (a + b) =
c) 8. (m + x) =
d) 5. (2 + 14) =
e) a (b + C) =
f)x×(3+b)
g)8×(2+a )
h)m×(x+y)
i)a×(x+y)
j)3×(4+a)​

Answer 1

Resposta:

a) 4. (3 + 5) =

$12+20=$

$32$

b) 2. (a + b) =

$2a+2b$

c) 8. (m + x) =

$8m+8x$

d) 5. (2 + 14) =

$10+70=$

$80$

e) a (b + C) =

$ab+ac =$

f)x×(3+b)

$3x+xb$

g)8×(2+a )

$16+8a=\\8a=-16\\a=\frac{-16}{8} \\a=-2$

h)m×(x+y)

$mx+my$

i)a×(x+y)

$ax+ay$

j)3×(4+a)​

$12+3a=\\3a=-12\\a=\frac{-12}{3} \\a=-4$
