Answer: 1. x^2-5x+4
2. x^2-7x+6
3. x^3-7x^2+11x-5
4. x-5
Step-by-step explanation:
1. x^2-6x+5+x-1=
x^2-6x+x+5-1=x^2-5x+4
2. x^2-6x+5-(x-1)=
x^2-6x+5-x+1=
x^2-6x-x+5+1=x^2-7x+6
3. (x^2-6x+5) * (x-1)=
x(x^2-6x+5)-1(x^2-6x+5)=
x^3-6x^2+5x-x^2+6x-5=
x^3-6x^2-x^2+5x+6x-5=x^3-7x^2+11x-5
4. (x^2-6x+5)/(x-1)=
(x^2-x-5x+5)/(x-1)=
(x(x-1)-5(x-1))/(x-1)=
(x-5)(x-1)/(x-1)=x-5
<span>A es falso porque podría dividirse por negativo.
B es verdadero porque el divisor siempre entrará en el dividendo.
C es falso porque cambiar el orden dará lugar a respuestas diferentes.
D es falso porque la propiedad asociativa no se aplica a la división.
E es falso porque no es "solo suficiente", aún necesita asegurarse de que el dividendo sea un número entero y el divisor sea un factor del dividendo.</span>
Answer:
7 weeks
Step-by-step explanation:
80 ÷ 20 = 4
She over those four week she makes 17 per week. So,
17 × 4 = 68
Next, divide the product by 20:
68 ÷ 20 = 3.4
But 3.4 is only 3 full weeks so then its 3.
Lastly, add the 3 weeks we just solved for the the 4 weeks from before and you get 7 weeks.
So, Anna will be able to supply the "Unique" store for 7 weeks.
I HOPE I HELPED!!!!!!!!!! :))))))
Answer:

Answer:
Step-by-step explanation:
a+b+c=0, a+b=-c,a+c=-b, b+c=-a
(a+b+c)^3=(a+b+c)^2*(a+b+c)=(a^2+b^2+c^2+2ab+2ac+2bc)*(a+b+c)=
a^3+ab^2+ac^2+2a^2b+2a^2c+2abc+a^2b+b^3+bc^2+2ab^2+2abc+2b^2c+a^2c+b^2c+c^3+2abc+2ac^2+2bc^2=a^3+b^3+c^3+3a^2b+3a^2c+3ac^2+3ab^2+3bc^2+3b^2c+6abc=
a^3+b^3+c^3+3a^2*(b+c)+3c^2(a+b)+3b^2(a+c)+6abc=
a^3+b^3+c^3+3a^2*(-a)+3c^2*(-c)+3b^2*(-b)+6abc=
a^3+b^3+c^3-3a^3-3c^3-3b^3+6abc=
6abc-2a^3-2b^3-2c^3=2(3abc-a^3-b^3-c^3)=
2*[3abc-(a^3+b^3+c^3)]=0
so 3abc-(a^3+b^3+c^3)=0
so a^3+b^3+c^3=3abc
