What is the complete factorization of the polynomial below? x3 + 8x2 + 19x + 12
O A. (x+4)(x+3)(x+1)
O B. (x + 4)(x-3)(x - 1)
C. (x+6)(x + 2)(x+1)
O D. (x+6)(x-2)(x-1)

Your answer is A

(wjjduwbsheh)

Almons:walnuts:rasins=1:2:3

x=pounds of walnuts
y=pounds of almonds
z=pounds or rasins
2x=y
3x=z
subsitute

12x+9y+5z=15
12x+9(2x)+5(3x)=15
12x+18x+15x=15
45x=15
divide by 45
x=1/3
so
1/3 pound of walnuts
2x=y
2(1/3)=y=2/3
2/3 pounds of almonds
3x=z
3(1/3)=z
1=z
1 pound of rasins

1/3 pound walnuts
2/3 pound almonds
1 pound rasins
