<u>Answer:</u>
The correct answer option is D. .
<u>Step-by-step explanation:</u>
We are given the following expression and we are to simplify it:
Here the variables and
are having negative powers. So to change these powers from negative to positive, we will take their reciprocals to get:
The scale ratio of a point A to another point B is the division of the length of B by the length of A. The best equation that models the situation is:
The page dimension is:
The length and the width of Uche's book are equal; this means the pages of Uche's book have the shape of a square
The margin of 0.75 on either sided means the usable dimension is:
The dimension of India is:
The longest side in India's dimension is:
From Uche's book, the longest dimension is:
So, the scale equation is:
k * longest length of Uche's book = longest side of India
This gives:
