The answer is 12!.....which is just the product of the first 12 positive integers

On the calculator, just key in  "12!".......the answer will be  ....   479,001,600

In fact, the way to arrange any N objects is just N!

Well ....if we have    (3n - 5)^20, the 20th term is just  C(20,20)(3n)^0(-5)^20  = 1*1*95367431640625  =  95367431640625

If  (3n - 5) is raised to a greater power, we would need to know what that power might be before an answer could be given........

T = 3U/E  multiply both sides by E

ET  = 3U   divide both sides by 3

( ET) / 3   =  U

-(3 + 5/8) - (1 + 1/2) =

-3 - 1  - 5/8 - 1/2  =

-4  - 5/8  - 4/8  =

-4 - 9/8  =

-4 - 1 - 1/8 =

-(5 + 1/8)

The opposite of an opposite is just the number we started with.....!!!!

Example

17 opposite = -17

-17 opposite = 17

I think you mean that the high temperature was withn 4 degees C either side of 18C if so, we have

l x - 18 l  <  4    and this means that

-4 < x - 18 < 4     add 18 to everything

14 < x < 22

This means that the temperature could have ranged anywhere from 14C to 22C, but not including either value.....

I'm assuming that you might have something like this  :

⁶sqrt(64)

Just key in......... (64) ^(1/6)   = 2

1. Steak

2. Pizza

3. Fried Chicken

[ In any order ........!!! ]

Nice answer, Dragonlance.......[ I think you meant to write 182/350..... but........we get the general idea.....  !!!!]

Also very nice in realizing that BOTH sides must be painted.....!!!!

if y=x^2-3x-4   and y=-4 what is x

-4 = x^2 - 3x - 4       add 4 to  both sides

x^2 - 3x = 0     factor

x(x -3) = 0      and setting each factor to 0, x = 0  or x = 3
