The first step when factoring any polynomial is to factor out the GCF. The GCF is the greatest common factor for all the terms of the polynomial. By factoring out the GCF first, the coefficients and constant term of the polynomial will be reduced.

<span>If there is a common factor, factor out the GCF. </span>The first step in factoring any polynomial is to determine whether the terms of the polynomial have a greatest common factor. If yes, factor it out first.

Naddika [18.5K]

Answer:

d = 11

Step-by-step explanation:

10 - d = -34 - 5d

10 (- d + d) = -34 (- 5d + d)

10 = -34 - 4d

10 + 34 = (-34 + 34) - 4d

44 = 4d

44/4 = 4d/4

d = 11

Simplify: 16z8-23z8 <br><br>enter the original expression if it can't be simplified

inn [45]

Answer:

The simplified version of that equation would be $-7z^{8}$ .

Step-by-step explanation:

Since $16z^{8}$ and $23z^{8}$ have the same exponent and variable, we can combine them normally.

$16z^{8}$ - $23z^{8}$ = $-7z^{8}$

Determine

Luden [163]

Answer:

$\mu_{x} = 64, \sigma_{x} = 12.83$

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sample means with size n of at least 30 can be approximated to a normal distribution with mean $\mu_{x} = \mu$ and standard deviation $\sigma_{x} = \frac{\sigma}{\sqrt{n}}$

In this problem, we have that:

$\mu = 64, \sigma = 77, n = 36$

$\mu_{x} = 64, \sigma_{x} = \frac{77}{\sqrt{36}} = 12.83$
