Answer:

114ft

Step-by-step explanation:

3 times 3=9

9times 2=18

8 times 3=24

24 times 2=48

Which is the greatest common factor of the expression below?<br> 32a²b2 + 36a²c2 – 16ab3
yKpoI14uk [10]

Answer:

Step-by-step explanation:

32a²b²  = 2 * 2*2*2*2 * a² * b²

36a²c² = 2 * 2 * 3 * 3 * a² * c²

16ab³  = 2 * 2 * 2* 2 * a * b³

Greatest common factor =  2*2*a = 4a

32a²b² + 36a²c² - 16ab³ = 4a*(8ab² + 9ac² - 4b³)

Brand A: 240 MG sodium for 1/3 pickle or Brand B: 325 MG sodium for 1/2 pickle
Blababa [14]
<span><u>Brand A:</u>
240 mg sodium in 1/3 pickle ===> 720 mg sodium in a whole pickle.

<u>Brand B:</u>

325 mg sodium in 1/2 pickle ===> 650 mg sodium in a whole pickle.

When I feel like enjoying a pickle, I would choose one from Brand A.
A nice firm, natural, organic, green Brand A would be more effective
at treating my sodium deficiency without pills or medication or other
kinds of un-natural chemicals. 

To make it even more healthy, I can squeeze the juice of a plump Brand A
onto my daily 5-egg cheese omelet, and treat my cholesterol deficiency at
the same time.</span>

A student claims that 2i is the only imaginary root of a polynomial equation that has real coefficients. Explain the student's m
____ [38]

Answer:

The Fundamental Theorem of Algebra assures that any polynomial  f(x)=0 whose degree is n ≥1 has at least one Real or Imaginary root. So by the Theorem we have infinitely solutions, including imaginary roots ≠ 2i

Step-by-step explanation:

1) This claim is mistaken.

2) The Fundamental Theorem of Algebra assures that any polynomial  f(x)=0 whose degree is n ≥1 has at least one Real or Imaginary root. So by the Theorem we have infinitely solutions, including imaginary roots ≠ 2i with real coefficients.

a_{0}x^{n}+a_{1}x^{2}+....a_{1}x+a_{0}

For example:

3) Every time a polynomial equation, like a quadratic equation which is an univariate polynomial one, has its discriminant following this rule:

\Delta < 0\\b^{2}-4*a*c

We'll have <em>n </em>different complex roots, not necessarily 2i.

For example:

Taking 3 polynomial equations with real coefficients, with

\Delta < 0

-4x^2-x-2=0 \Rightarrow S=\left \{ x'=-\frac{1}{8}-i\frac{\sqrt{31}}{8},\:x''=-\frac{1}{8}+i\frac{\sqrt{31}}{8} \right \}\\-x^2-x-8=0 \Rightarrow S=\left\{\quad x'=-\frac{1}{2}-i\frac{\sqrt{31}}{2},\:x''=-\frac{1}{2}+i\frac{\sqrt{31}}{2} \right \}\\x^2-x+30=0\Rightarrow S=\left \{ x'=\frac{1}{2}+i\frac{\sqrt{119}}{2},\:x''=\frac{1}{2}-i\frac{\sqrt{119}}{2} \right \}\\(...)

2.2) For other Polynomial equations with real coefficients we can see other complex roots ≠ 2i. In this one we have also -2i

x^5\:-\:x^4\:+\:x^3\:-\:x^2\:-\:12x\:+\:12=0 \Rightarrow S=\left \{ x_{1}=1,\:x_{2}=-\sqrt{3},\:x_{3}=\sqrt{3},\:x_{4}=2i,\:x_{5}=-2i \right \}\\
