Anumber multiplied by 12 is equal to the sum of the square root of that same number and 36. what is that number?

3.15

Step-by-step explanation:

Let the unknown number be n.

Then 12n = √n + 36

We must eliminate the √ operator.  One way to do this is to replace √n temporarily with x.  Then 12n = 12x^2, and we have 12x^2 - x - 36 = 0.  This is a quadratic with a= 12, b= -1 and c = -36

Solving for x using the quadratic formula:

       1 plus or minus √(1 - 4(12)(-36)

x =

                        2(12)

      1 plus or minus √1729

x =

                        24

       1 plus or minus 41.58

x =

                    24

Since x = √n, n must be a positive number.  Thus,

       1 + 41.58

x = = 1.77

            24

If x = 1.77 = √n, then n = 1.77^2 = 3.15.

Check:  Is this true?  A number multiplied by 12 is equal to the sum of the square root of that same number and 36.

12(3.15) = √3.15 + 36, or

 37.8    =  1.77 + 36  = 37.77     This checks out.

The number is 3.15

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
