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

Answer:

Step-by-step explanation:
Multiply numerator and denominator by the "conjugate" of the denominator.

__
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)

<u>RECIPROCAL</u></h2>
<h3>ANSWER: </h3>
<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.
Hence, 3/1 or 3 is the correct answer.
