The length of a rectangle is triple the width. If the area of the rectangle is 75 square inches, then find the length and width
Ronch [10]

Answer:

W = 5

L = 15

Step-by-step explanation:

Formula for Area of Rectangle is L × W

Since stated triple;

L = 3W

Area = L×W = 3W² = 75

It'll be:

3W² = 75

Divide both sides with 3:

<u>3</u><u>W</u><u>²</u> = <u>7</u><u>5</u>

3 3

W² = 25

Then square root both sides:

w = 5

Again stated that length is triple the width:

L = 5 × 3

L = 15

Therefore;

W = 5

L = 15

The question is this: Rationalize the denominator and simplify.
Neko [114]

9514 1404 393

Answer:

  \dfrac{20+5\sqrt{3}}{13}

Step-by-step explanation:

Multiply numerator and denominator by the "conjugate" of the denominator.

  \dfrac{5}{4-\sqrt{3}}=\dfrac{5(4+\sqrt{3})}{(4-\sqrt{3})(4+\sqrt{3})}=\dfrac{20+5\sqrt{3}}{4^2-(\sqrt{3})^2}=\boxed{\dfrac{20+5\sqrt{3}}{13}}

__

This is done in different scenarios in order to take advantage of the factoring of the difference of squares. Square root terms and imaginary terms in the denominator can be eliminated in this way.

  a² - b² = (a -b)(a +b)

Write down the reciprocal of<br> 1/3
Leokris [45]
<h2><u>RECIPROCAL</u></h2>

<h3>ANSWER: </h3>
  • \boxed{ \bold{3 \: \: \:  or  \: \:  \:  \frac{3}{1} }}

<h3>EXPLANATION:</h3>

As we can see above, it's clear that 3 and 1/3 are reciprocals of each other.

And we can find the reciprocal of 1/3 by forming a fraction and to multiply the numerator and denominator by 3.

  • \\ \large  \tt \:  \frac{1 \times 3}{ \frac{1}{3} \times 3 }  =  \bold{ \frac{3}{1}  = 3} \\ \\

Hence, 3/1 or 3 is the correct answer.
