2x(x - 2) + 3x  =  -3(3x + 1)

 2x² - 4x + 3x  =  -9x - 3

            2x² - x =  -9x - 3

        2x² + 8x  =  -3

  2x² + 8x + 3  =  0

a = 2,  b = 8,  c = 3

x  =  [ -b +/- sqrt( b² - 4ac ) ] / ( 2a )

x  =  [ -8 +/- sqrt( 8² - 4·2·3 ) ] / ( 2·2 )

x  =  [ -8 +/- sqrt( 64 - 24 ) ] / 4

x  =  [ -8 +/- sqrt( 40 ) ] / 4

x  =  [ -4 +/- sqrt( 10 ) ] / 2

8(x + 1)  =  -2x + 1

  8x + 8  =  -2x + 1                     [using the distributive property]

 10x + 8  =  1                             [adding 2x to both sides]

       10x  =  -7                            [subtract 8 from both sides]

           x  =  -7/10                       [divide both sides by 10]

(a + b)²

=  (a + b)(a + b)

=  a·(a + b) + b·(a + b)

=  a·a + a·b + b·a + b·b

=  a² + a·b + a·b + b²

=  a² + ab + ab + b²

=  a² + 2ab + b²

50000-100000

or

50000*-1

I really don't know but I think there is an option on the caculator where you get a answer where you can click it and it gives you options on what you want the caculator to do

Anyone able to help me? I am working on my HW and need a little help with estimating quantities

4+6x4-8/10+2=16 dude

16!

This is just the "formula" for   13C10  =  286

Use this →     given degrees  x   [ pi ] / 180

$3514.65  +   $5674.25  - $1207.03   = $7981.90  profit

z / 2  + 1  ≤  7      subtract 1 from both sides

z / 2  ≤  6    multiply both sides by 2

z ≤  12

 ( √[2⁶] ) ²  =   2⁶ =   64

1/ [2/3] X 5/6   =

3/2 x  5/6  =

15 / 12  =

5 / 4

hola

f(x)= -2/3 * x2 - x  +5, f(6)

This just means that we want to put 6 into the function and evaluate....so we have

(-2/3)(6)^2  - 6 + 5   =   -24 - 6 + 5   =  -30 + 5  = -25

I = Prt      divide both sides by  rt

I / [rt]  = P       "3" is the correct response

Look at he graph, here: https://www.desmos.com/calculator/lgnpwgfwaj

There are two occurences when f(x)  = x

In the third function......f(x)  = x  when x =   3 + 1/3 

And in the fourth function, f(x)  = x when x = 5
