Question

Ayuden porfaaaaaaaa.

Answer 1

Respuesta:

P = 5

Explicación paso a paso:

• x*y = 4

• x + y = 6

(x + y)^2 = (6)^2

x^2 + 2*x*y + y^2 = 36

x^2 + 2*(4) + y^2 = 36

x^2 + y^2 = 36 - 8

x^2 + y^2 = 28

• x^2 + y^2 = 28

(x^2 + y^2)*(x + y) = 28*(x + y)

x^3 + x^2*y + x*y^2 + y^3 = 28*6

x^3 + y^3 + x*y*(x + y)  = 168

x^3 + y^3 + (4)*(6)  = 168

x^3 + y^3 + 24  = 168

x^3 + y^3 = 168 - 24

x^3 + y^3 = 144

Determinar:

P = (x^3 + y^3 - 4) / ( x^2 + y^2)

P = (144 - 4) / (28)

P = 5
