Question

me podrian ayudar por favor es urgente, de esto depende una calificacion aprobatoria o reprobatoria e irme a un extraordinario
(2a+3b+c)+(5b+8c+a)
(z+12+y)+(10z+4y+11x)
(3a-6b)+(4a+8b)
(4x+7y-4z)+(6x-7y+4z)
2x(x+3)
(x-2)(x-3)
3x(x-4)
(x-2)(x-y+2)
(x+2)(x+2)2x(x+2)
-(2x+5)=-2(3x+4)+19

Answer 1

Explicación paso a paso:

(2a+3b+c)+(5b+8c+a)

2a+3b+c+(5b+8c+a)

2a+3b+c+5b+8c+a

3a+8b+9c

(z+12+y)+(10z+4y+11x)

z+12+y+(10z+4y+11x)

z+12+y+10z+4y+11x

11x+5y+11z+12

(3a-6b)+(4a+8b)

3a-6b+(4a+8b)

3a-6b+4a+8b

8a+2b

(4x+7y-4z)+(6x-7y+4z)

4x+7y-4z+(6x-7y+4z)

4x+7y-4z+6x-7y+4z

10x

2x(x+3)

2x²+6x

(x-2)(x-3)

x²-3x-2x+6

x²-5x+6

3x(x-4)

3x²-12x

(x-2)(x-y+2)

x²-xy+2x-2x+2y-4

x²-xy+2y-4

(x+2)(x+2)2x(x+2)

x²+2x+2x+4+2x²+4x

2x^4+12x³+24x²+16x

-(2x+5)=-2(3x+4)+19

-2x-5=-2(3x+4)+19

-2x-5=-6x-8+19

4x=11+5

4x=16

x=16/4

x=4

Answer 2

Respuesta:

Explicación paso a paso:

(2a+3b+c)+(5b+8c+a)= 2a+3b+c+5b+8c+a =3a +8b+9c

(z+12+y)+(10z+4y+11x) = z+12+y+10z+4y+11x = 11x +5y +11z +12

(3a-6b)+(4a+8b) =3a-6b+4a+8b = 7a + 2b

(4x+7y-4z)+(6x-7y+4z) = 4x+7y-4z+6x-7y+4z = 10x

2x(x+3)   = 2x² + 6x

(x-2)(x-3)  = x² - 5x +6

3x(x-4)  = 3x² - 12x

(x-2)(x-y+2) = x²- xy + 2x - 2x +2y - 4= x²- xy 2y -4

(x+2)(x+2)2x(x+2) ² revisar el enunciado

-(2x+5)=-2(3x+4)+19

-2x - 5 = -6x - 8 +19

-2x+6x = 5-8 +19

      4x = 16

        x = 4
