Question

Aplique a propriedade distributiva nas expressões algébricas:

3 (x+ 5) =

2 (9 -x) =

-5 (2x+ 4) =

4 (x + 3) =

2/3 (x -1) =

– 3 (x/3 + 5) =

​

Answer 1

Resposta:

a) 2(a+4)= 2a+8

b)5 (2a-1)= 10a-5

c)-4 (2x-3)=-8x+12

d)10 (3a-2b+1)= 30a-20b+10

e)3 (x+2)+2(2x-1)-x+2

3x+6+4x-2-x+2

7x-x+6-2+2

=6×+6

f)5×+10y-5-6x+3y-3-x+2

5x-7x+13y-5-3+2

-2×+13y-8+2

-2x+13y-6
