Answer:

x = 5

Step-by-step explanation:

Step 1: Distributive property

Using this property means when you have something like the equation on the right side ( 4 ( x + 3 ) ) you multiply both the values in the parentheses by the number outside:

4 ( x + 3 )

( 4 x X ) + ( 4 x 3 )

4x + 12

8x + 2 = 2x + 4x + 12

Step 2: combine like terms

Combining like terms is when you find like terms with the same variables and such and add them together:

8x + 2 = 12 + ( 2x + 4x )

8x + 2 = 12 + 6x

Step 3:Using inverse operations

This means that you need to get a variable one one side and a constant on the other:

8x + 2 ( -2 ) = 12 ( -2 ) + 6x

8x = 10 + 6x

8x ( -6x ) = 10 + 6x ( -6x )

2x = 10

Step 4: solve for the variable

The last thing you need to do is divide both sides by the constant with the variable ( 2x ) to get x by itself:

2x ( /2 ) = 10 ( /2 )

x = 5

Answer:

x=5

Step-by-step explanation:

Step 1:Using the distributive property on the right side of the equation

8x+2=2x+4(x+3)

8x+2=2x+4x+12

Step2:Combining the like terms on the right side if the equation (Since there are no like terms on the left side) :

8x+2=6x+12

Step 3: Using the inverse operations to get the variables on the left side and the constants on the right side of the equation :

8x-6x=12-2

Step4: Using inverse operation to solve for the variable of interest which is 'x':

2x=10 (Dividing both sides by two sides by 2)

x=5

Answer:

f(x) = $x^4 - 2x^3 + 49x^2 - 18x + 360$ is the required polynomial.

Step-by-step explanation:

Given the zeroes (roots) of the polynomial are $-3i$ and $2 + 6i$ .

We know that complex roots occur in conjugate pairs.

So, this means that $+3i$ and $2 - 6i$ would also be the roots of the polynomial.

If $\pm 3i$ are to be the roots of the polynomial then the polynomial should have been: $x^2 + 9 = 0$ .

Now, to determine the polynomial for which $2 \pm 6i$ would be the roots.

Roots of the polynomial are nothing but the values of x (any variable) that would make the polynomial zero.

⇒ $x = 2 + 6i \hspace{35mm} x = 2 - 6i$

⇒ $x - 2 - 6i = 0 \hspace{25mm} x - 2 + 6i = 0$

The required polynomial would be the product of all the above polynomials.

$i.e., (x^2 + 9)(x - 2 + 6i)(x - 2 - 6i) = 0$

Multiply this to get the required equation.

⇒ $(x^2 + 9)(x^2 - 2x + 40)$

$\implies x^4 - 2x^3 + 40x^2 + 9x^2 - 18x + 360 = 0$

∴ The required polynomial is x⁴ - 2x³ + 49x² - 18x + 360 = 0.

To be legal for certain types of prize competitions, bowling balls must be very close to 16 lb. The weights of bowling balls fro

PtichkaEL [24]

Answer:

The probability that a manufactured ball will be rejected is 0.99, to two decimal places.

Step-by-step explanation:

The mean weight is 16 Ibs. The standard deviation of the weights of all manufactured balls from the mean weight is 25. The distribution is normal. With a standard deviation this large, it is already obvious that there is a high probability of producing or having rejected balls. The weights of the balls produced here ranges from (16-25)Ibs to (16+25)Ibs.

That's -9Ibs to 41Ibs.

The minimum permissible weight is 15.68. Any ball with a lesser weight gets kicked out!

So the distance or difference between this figure and the mean is (16-15.68) = 0.32

So the probability of obtaining less than 15.68Ibs or the probability of having balls between the lower boundary of -9Ibs and 15.68 is:

25-0.32 = 24.68

24.68 ÷ 25 = 0.9872 ~ 0.99 to two decimal places.

Rachel is 10 years older than her sister, Renee. In six years from now, the sum of their ages will be 40. How old is each girl?

Arisa [49]

Answer: I say the answer is 20 years old, 30 years old

Step-by-step explanation: If rachel is 10 years old than her sister in six years from now, the sum of their ages will be 40. So rachel is 10 years older than her sister so the younger sister has to be 20 years old and and rachel is 30 years old.
