Answer:

See below.

Step-by-step explanation:

p^2 + 2

= (6n + 1)^2 + 2

= 36n^2 + 12n + 1 + 2

=  36n^3 + 12n + 3

= 3(12n^2 + 4n + 1).

- which is divisible by 3.

seropon [69]

Answer:

2x^3-8x^2+8x+12

Step-by-step explanation:

split them up

use distributive property

2x-6(x-2)

2x^2-4x-6x+12(x+1)

use distributive property again

2x^3+2x^2-4x^2-4x-6x^2-6x+12x+12

simplify

2x^3-8x^2+8x+12

I forgot if you can divide it by 2 or not to simplify it even more. If you can, divide it by 2. I forgot the rules

If you divide it by 2, then the answer is

x^3-4x^2+4x+6

ipn [44]

Answer:

The number of adults is 1,200

Step-by-step explanation:

Let

x------> the number of children

y------> the number of adults

we know that

x+y=1800 -------> equation A

2x+4y=6000 -------> equation B

Multiply equation A by -2

-2(x+y)=-2*1800 --------> -2x-2y=-3600 ------> equation C

Adds equation B and equation C

2x+4y=6000\\-2x-2y=-3600\\---------\\4y-2y=6000-3600\\2y=2400\\y=2400/2\\y=1200
