ARAT TIETE (Simplify): V125 - V45+ V5​

Mathematics
1 answer:
Nataly [62]2 years ago
6 0

Answer:

3\sqrt{5}

Step-by-step explanation:

Using the rule of radicals

\sqrt{a} × \sqrt{b} ⇔ \sqrt{ab}

Simplifying the radicals

\sqrt{125}

= \sqrt{25(5)}

= \sqrt{25} × \sqrt{5} = 5\sqrt{5}

\sqrt{45}

= \sqrt{9(5)}

= \sqrt{9} × \sqrt{5} = 3\sqrt{5}

Then

\sqrt{125} - \sqrt{45} + \sqrt{5}

= 5\sqrt{5} - 3\sqrt{5} + \sqrt{5} ← collect like terms

= 3\sqrt{5}

The slope for 5 and 2
Yuri [45]

\qquad\qquad\huge\underline{{\sf Answer}}♨

As we know, slope (m) is equal to tan θ for a straight line :

\qquad \tt\dashrightarrow \: m = \tan( \theta)

\qquad \tt\dashrightarrow \: m =  \dfrac{5}{2}

So, we can say that it's a positive constant slope

The side lenghts of a triangle are 14,15, and x units
iragen [17]

9514 1404 393

Answer:

  1 < x < 29

Step-by-step explanation:

The triangle inequality requires the sum of the two shortest sides exceed the longest side.

<u>When x and 14 are the shortest</u>:

  x + 14 > 15

  x > 1

<u>When 14 and 15 are the shortest</u>:

  14 +15 > x

  29 > x

Then the requirement for the length of x is ...

  1 < x < 29

_____

<em>Additional comment</em>

The length of the third side of a triangle can be between the difference and sum of the two given sides.
