Thank you very much melody

What is negative six to the 2nd power minus (bracket) 56 divided by (parenthesis) negative 17 plus thirty one (parenthesis) (bracket) plus 25

You would have been better off just putting the bracket symbol that you wanted. Yours was confusing but I think this is what you wanted.

\(-6^2-(56/\{-17+31\})+25\\ =-6^2-(56/\{14\})+25\\ =-6^2-(4)+25\\ =-6^2-4+25\\ =-36-4+25\\ =-40+25\\ =-15\)

What is negative six to the 2nd power minus (bracket) 56 divided by (parenthesis) negative 17 plus thirty one (parenthesis) (bracket) plus 25

-6^2 - [ 56 / ( -17 + 31) ] + 25 =

-36 - [ 56 / 14 ] + 25  =

-36 - 4 + 25  =

-15

Simplify the following:
9 (2 x+6/6)-2 (1-3 x)

6/6 = 1:
9 (2 x+1)-2 (1-3 x)

9 (2 x+1) = 18 x+9:
18 x+9-2 (1-3 x)

-2 (1-3 x) = 6 x-2:
6 x-2+18 x+9

Grouping like terms, 18 x+6 x-2+9 = (18 x+6 x)+(9-2):
(18 x+6 x)+(9-2)

18 x+6 x = 24 x:
24 x+(9-2)

9-2 = 7:

The top surface is given by :

81  =   s^2    →   s   =  9  in

And the volume of a cube   = s^3  = 9^3   =  729 cubic inches

( 7 /8)  / (1 / 24)   =

(7 / 8 ) * ( 24 / 1)  =

( 7 / 1) * ( 24 / 8 )  =

7 *   3    =

You mean Pi? Pie is something you eat for dessert!

Pi begins with these numbers:3.1415926535897932384626433832795.....................FOREVER.............etc.

No!!!!!....... the square root of -1  is not a real number   [ it's defined as " i "  ]

0 and 1 have equal cube and square roots

The edge =  (0.216)^1/3   = 0.6 in

No.....this is NOT true.....!!!!

cot x  = cosx / sin x

tan x =  sinx / cosx

So

cosx / sinx  not equal  to 2 sinx / cosx

There are at least 1000 different formulas for calculating Pi. You can download this program for free and you can calculate Pi to as many digits as you want.

2x - 7

Notice something :

(a / b)^-n    = (b / a )ⁿ     ......so......

(2 / 3)^-3   =  (3 / 2 )³ =  27 / 8

X*0.9929+0.0102       

X =  - 0.0102 / 0.9929  = about -0.01027

Definitely a real number..........!!!!

2^(-4) = 1/ 2^(+4)

1/2 b+9/4=7/4    multiply both sides by 4 to clear the fractions

2b + 9 = 7         subtract 9 from both sides

2b = -2             divide both sides by 2

b = - 1

|2x-6|=6   we have two equations, here

2x - 6   = 6            and         2x - 6  = -6

Add 6 to both sides

2x = 12                               2x  = 0 

Divide both sides by 2

x = 6            and                    x = 0

The binomial expansion of this is :

-729 x^3+1701 x^2-1323 x+343

x - 3 < 2   add 3 to both sides

x <  5

A. 150/250 B. 24/42 C. 75/135 D. 75/150

A = 60%

B = about 57%

C = about 56%

D = 50%

i'm gonna guess B: 24/42

I think you need to relearn functions. A function is therefore a many-to-one (or sometimes one-to-one) relation. The set of values at which a function is defined is called its domain, while the set of values that the function can produce is called its range. mathworld.wolfram.com/Function.html
