08) Aplique a propriedade distributiva e reduza os termos semelhantes.

a) 2.(X + 8) + 5x - 2 =

b) 3.(2Y - 2) - y + 23 -

c) 8.(m-5) + 7.(m + 3) =

d) 7x + 8.(3x-4)

e) -(2x + 7) + 2.(3x - 11) =​​

Answer 1

a) 2.(x + 8) + 5x - 2 =
2x + 16 + 5x - 2 =
7x + 14

b) 3.(2y - 2) - y + 23 =
6y - 6 - y + 23 =
5y - 17

c) 8.(m - 5) + 7.(m + 3) =
8m - 40 + 7m + 21 =
15m - 19

d) 7x + 8.(3x - 4) =
7x + 24x - 32 =
31x - 32

e) -(2x + 7) + 2.(3x - 11) =
-2x + 7 + 6x - 22 =
4x - 15
