b)8x+5x-13x
c)3x+4x^3-5x+x^3+2x
d)5z+11t-6t+2z

Answer 1

Resposta:

a) 13a+8x-2a+3x=

13a-2a+8x+3x=

11a+11x=

11 (a+x)

b) 8x+5x-13x=

13x-13x=0

c)

$3x + {4x}^{3} - 5x + {x}^{3 } + 2x = \\ {4x}^{3} + {x}^{3} + 3x + 2x - 5x = \\ 5 {x}^{3} + 5x - 5x = \\ 5 {x}^{3}$

d) 5z +11t-6t+2z=

5z+2z+11t-6t=

7z+5t

Answer 2

Resposta:

a) 11a+11x

b)13x-13x=0

c)3x+64x-5x+3x+2x= 67x
