Help please I will mark brainlest
rodikova [14]

Answer:

5\sqrt{7}

Step-by-step explanation:

\frac{30\sqrt{14} }{6\sqrt{2} }

Cancel out 6 in both numerator and denominator.

\frac{5\sqrt{14} }{\sqrt{2} } Rationalize the denominator of \frac{5\sqrt{14} }{\sqrt{2} } by multiplying the numerator and denominator by \sqrt{2}.

\frac{5\sqrt{14}\sqrt{2}  }{(\sqrt{2})^{2}  }

The square of  \sqrt{2} is 2

Factor 14=2 × 7. Rewrite the square root of the product \sqrt{2x7} as the product of square roots \sqrt{2}\sqrt{7}.

\frac{5\sqrt{2}\sqrt{7}\sqrt{2}   }{2}

Multiply \sqrt{2} and \sqrt{2} to get 2.

\frac{5x2\sqrt{7} }{2}

Cancel out 2 and 2.

5\sqrt{7}

Hope it helps and have a great day! =D

1. Which of the following is an irrational number? How do you know? Use key words and definitions to explain your answer choice.
Angelina_Jolie [31]

1:-

0.25

  • it should be in p/q form

\\ \rm{:}\twoheadrightarrow 0.25

\\ \rm{:}\twoheadrightarrow \dfrac{25}{100}

\\ \rm{:}\twoheadrightarrow \dfrac{1}{4}

  • q not equal to zero hence proved

2:-

Its Slightly false.

Counter example :-

The sum of two rational numbers is may be rational. The sum of two irrational numbers is always irrational.”

ex:-

\\ \rm{:}\twoheadrightarrow \dfrac{1}{2}+\dfrac{1}{2}

\\ \rm{:}\twoheadrightarrow 1

3:-

NOTA

\\ \rm{:}\twoheadrightarrow 6(94)+7+(3+2)

\\ \rm{:}\twoheadrightarrow 564+7+5

\\ \rm{:}\twoheadrightarrow 576

The ordered pairs (3,2) and (-2,13) are points on a linear function. Which equation best describes this function?
Mars2501 [29]

Answer:

The equation which describe this function is 5x + 11y = 37

Step-by-step explanation:

<u>To find the slope</u>

slope = (y₂ - y₁)/(x₂ - x₁)

slope = (13 - 2)/(-2 - 3) = 11/-5

<u>To find the equation</u>

(x - 3)/(y - 2) = -11/5

5(x - 3) = -11(y - 2)

5x -15  = -11y + 22

5x + 11y = 22 + 15

5x + 11y = 37

Therefore the equation which describe this function is

5x + 11y = 37

You're given a table of x values and an equation. To solve, plug in the values for x.

First box: y=2(-3)-1=-7
Second box: y=2(-2)-1=-5.

See if you can solve the third one.
