Answer:

The solution to the equation are x = 5.089  and    x = -0.589

Step-by-step explanation:

Given:

x(at the power of 2) = 6 + 9x

To Find:

The solution of the equation = ?

Solution:

The given equation can be written as  

=> 2x^2 = 6+9x

=>2x^2-6 -9x=0

=>2x^2-9x-6=0

Using the quadratic formula,

x = \frac{-b\pm \sqrt{(b^2 -4ac}}{2a}

where

a= 2

b = -9

c = -6

Substituting these values,

x = \frac{-(-9)\pm \sqrt{(-9)^2 -4(2)(-6)}}{2(2)}

x = \frac{-(-9)\pm \sqrt{(81) -4(-12)}}{2(2)}

x = \frac{-(-9)\pm \sqrt{81+48}}{4}

x = \frac{-(-9)\pm \sqrt{129}}{4}

x = \frac{-(-9)\pm 11.357}{4}

x = \frac{9 \pm 11.357}{4}

x = \frac{9 + 11.357}{4}                        x = \frac{9 - 11.357}{4}

x = \frac{20.357}{4}                            x = \frac{-2.357}{4}  

x =5.089                                                           x =   -0.589

wariber [46]

Answer:

A)  \frac{3}{12}

Step-by-step explanation:

Given:

Jing is helping the kindergarten teacher put together bags of crayons.

Each bag has 4 crayons, and 1/4 of the crayons in each bag are green.

What fraction of the crayons in 3 bags are green?

<u>Solution:</u>

1 bag contains number of crayons = 4

1 bag contains number of green crayons = \frac{1}{4} \ of\ 4 = \frac{1}{4}\times4=1

Total number of bags = 3

Total number of crayons in 3 bags = 4 \times 3 = 12

1 bag contains number of green crayons = 1

Total number of green crayons in 3 bags = 1  \times 3 = 3

Fraction of the green crayons out of total = 3 out of 12 = \frac{3}{12}

Therefore, fraction of the crayons in 3 bags are green are  \frac{3}{12}

If AC = 14, find the value of x. Then find AB and BC.
stira [4]

<em>Your question is incomplete; However, a similar question is:</em>

<em>If B is between A and C, AB = x, BC = 2x + 2, and AC = 14, find the value of x. Then find AB and BC.</em>

<em></em>

<em>This should serve as a guide</em>

Answer:

See Explanation

Step-by-step explanation:

Given

AB = x

BC = 2x + 2

AC =14

Required

Determine x, AB and BC.

Since B is between A and C;

AB + BC = AC

Substitute x for AB; 2x + 2 for BC and 14 for AC

x + 2x + 2 = 14

3x + 2 = 14

Collect Like Terms

3x = 14 - 2

3x = 12'

x = \frac{12}{3}

x = 4

Substitute 4 for x in

AB = x

BC = 2x + 2

AB = 4

BC = 2(4) + 2

BC = 8 + 2

BC = 10
