A(b^2+c^2+bc) + b(c^2+a^2+ca) + c(a^2+b^2+ab)

zaharov [31]

Answer:

(a-b)(b-c)(a-c)

Step-by-step explanation:

a^2(b - c) + b^2(c-a) + c^2(a - b)

= a^2b - a^2c + b^2c - b^2a + c^2a-c^2b

=a^2b - b^2a - a^2c + b^2c + c^2a -c^2b

= ab(a - b) - c(a^2 - b^2) +c^2(a - b)

=ab(a - b) -c(a - b)(a + b) +c^2(a - b)

=(a - b)(ab - c(a + b) +c^2)

=(a - b)(ab - cb -ca + c^2)

= (a - b)(b(a-c) -c(a-c))

=(a-b)(b-c)(a-c)

There are 12 cookies in a container. There are 12 containers packed in a box for shipping. There are 12 boxes loaded onto a ship

mamaluj [8]

Option A

Total number of cookies on a shipping truck when 12 boxes are loaded is 1728.

Solution:

Need to determine correct option of total number of cookies on the truck

From given information

Number of cookies in 1 container = 12

Number of container in 1 box = 12

So number of cookies in 1 box = number of cookies in 12 container

$\Rightarrow \text { Number of cookies in } 1 \text { box }=\text { number of cookies in } 1 \text { container } \times 12$

$=12 \times 12=144$

Number of boxes loaded onto 1 shipping truck = 12

So Number of cookies onto 1 shipping truck = number of cookies in 12 boxes

$\Rightarrow \text { Number of cookies onto } 1 \text { shipping truck }=\text { number of cookies in } 1 \text { box } \times 12$

$=144 \times 12=1728$

Hence total number of cookies on a shipping truch when 12 boxes are loaded is 1728. Thus option A is correct
