To solve this problem, we want to make sure the denominators are the same on both fractions. Once they are equal, we can dd them together.
[multiply first fraction by y+4 and second by y-8]
[distribute by FOIL]
[add numerator]
[combine like terms]
[factor out 2 from numerator]

Answer: 24</h3>
Explanation:
x = smaller number
8x = larger number, since it's 8 times larger than the smaller
8x-x = 7x = difference of the numbers
That difference is 21, so we can say 7x = 21 which solves to x = 3
The smaller number is 3 and the larger is 8x = 8*3 = 24
As a check: 24-3 = 21, which confirms the answer.
The area of that shape is: 200 cm
The perimeter of that shape is: 72 cm
