Question

gente pfv o tempo pra enviar ta quase acabando

Answer 1

Resposta:

a) A + B = -11/15x

b)A-B = 1/15x

c)B-A = -1/15x

d)AxB = 2/15x^2

e)A/B= 5/6

Explicação passo-a-passo:

a) A + B = -1/3x -2/5x = -5/15x -6/15x=-11/15x

b)A-B = -1/3x -(-2/5)x = -1/3x + 2/5x=-5/15x +6/15x = 1/15x

c)B-A =-2/5x +1/3x= -6/15x + 5/15x= -1/15x

d)AxB = 2/15x^2

e)A/B= 5/6
