What is the missing value in the equation
2 3/12+3\? =2 5/8

 2 3/12 +3/x = 2 5/8

simplify to

9x+12/4x = 21/8

Cross multiply

(9x+12)/(4x) = 21/8

(9x+12)*(8) = 21*4x

72x+96 = 84x

Subtract 84 x from both side

72x+96 - 84x = 84x -84x

-12x+96 = 0

Subtract 96 from both sides

-12x+96-96 = 0-96

-12x = -96

Divide both sides by 12

-12x/-12 = -96/-12

x = 8

The missing value is 8

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

//blooming serenity//

beautiful in the morning

mysterious at night

wonderous nature souring

with all it's mystical might

the flower that blooms

to the fox that looms

nocturnal creatures

with various features

a blooming flower soon in sight

as a new little hatchling fears to take flight  

afraid to leave it's calming nest,

but dear little bird, mother knows best

as sure as there are stars in the sky,

life is not about who, where what, when or why-

it's the journey that follows

adventures we swallow

of   nature's deep wonders,

natural disasters and storm's thunders.

blooming serenity

life and nature, truly is heavenly.
