A) 4(x-1)+3(x-1)=

B) -2(x-4)+5(-2x-10)=

C)2(x+6)+3(x-1)=

D)3(3x-3)+2(5x+4)=​

Answer 1

Resposta:

A) 7x - 7

B) - 12x - 42

C) 5x + 9

D) 19x - 1

Explicação passo-a-passo:

A) 4(x - 1) + 3(x - 1)

4x - 4 + 3x - 3

7x - 7

B) -2(x - 4) + 5(-2x - 10)

- 2x + 8 - 10x - 50

- 12x - 42

C) 2(x + 6) + 3(x - 1)

2x + 12 + 3x - 3

5x + 9

D) 3(3x - 3) + 2(5x + 4)

9x - 9 + 10x + 8

19x - 1
