alguem sabe responder isso por favor é pra 17:25​

Answer 1

A) 5ax - 6 (a - ax) - (-2a - 7ax²)

    5ax - 6a + 6ax + 2a + 7ax²

    7ax² + 11ax - 4a

B) (-9x + 10) - (2x - 2) + (-x - 3) - (9x + 10)

    - 9x + 10 - 2x + 2 - x - 3 - 9x - 10

    - 9x - 2x - x - 9x + 10 + 2 - 3 - 10

    - 21x - 1

Answer 2

A) 5ax-6(a-ax)-(-2a-7ax²)

= 5ax-6a+6ax+2a+7ax²

= 7ax²+5ax+6ax+2a-6a

= 7ax²+11ax-4a

B) (-9x+10)-(2x-2)+(-x-3)-(9x+10)

= -9x+10-2x+2-x-3-9x-10

= -9x-2x-x-9x+10+2-3-10

= -21x-1
