Let
be the side length of the small square. Then, the side length of the big square is
.
The respective areas are
and 
So, the sum of the areas are 
We have

We can't have negative lengts, so we choose 
So, the side length of the larger square is 6.
For this case we propose a rule of three:
25 ------------> 100%
2 --------------> x
Where the variable "x" represents the percentage equivalent to 2 doctors.

Thus, 2 doctors represent 8% of 25
Answer:
2 doctors represent 8% of 25
To add fractions together, you must convert the smaller fraction (
) to a denominator that matches the other fractions denominator.
In this case, 1/2 would become 4/8
We can add 4/8 to 7/8 to get 11/8
Then we can add the 1 to it, which acts as 8.
Which gives us 19/8
Or 2 3/8
Answer: 6x^7+ 12x^6+ 3x^5
