Me podrian ayudar con esto porfa

Answer 1

Respuesta:

Explicación paso a paso:

1. G.A(x) = 2a + 4 = 14

2a + 4 = 14

a = 5

2.

P(x) = 2/5(x+2)(x-3)

P(1) = (2/5)(1+2)(1-3) = (2/5)(3)(-2) = -12/5

P() = 2/5(4+2)(4-3) = 2/5(6)(1) = 12/5

E = P(1) + P(4)

E =  -12/5 + 12/5 = 0

P(x,y) = (3/7)(x-7)(y-3)

P(1,2) = (3/7)(1-7)(2-3) = (3/7)(-6)(-1) = 18/7

P(7,6) = (3/7)(x-7)(y-3)  = (3/7)(0)(3) = 0

E = P(1,2) + P(7,6) = 18/7

3.

G.R(y) = 10

b+3 = 10

b = 7

suma de coeficinetes = 1 - 4 + b = -3 + 7 = 4

4.

G.A = a + b + 4 = 10 , a+b = 6

suma de coeficientes :

a + b + 3 = 9
