Question

(x+5)-(x+2)-x>7
Por favor me ajudem

Answer 1

(x+5)-(x+2)-x≥7
x²+2x-5x+10-x≥7
x²-4x+10-7≥0
x²-4x+3=0
x=-b+-√b²-4*a*c/2*a
x=4+-√16-12/2
x=4+-4/2
x=4+4/2
x=8/2      x=4
x=4-4/2
x=0/2
x=1

Answer 2

Resposta:

x < -4

Explicação passo-a-passo:

(x+5)-(x+2)-x>7

x + 5 - x - 2 - x > 7

-x + 3 > 7

- x > 7 -3

-x > 4 .(-1)

x < -4

Bons Estudos :)
