![w^{2} + 8w + 16](https://tex.z-dn.net/?f=%20w%5E%7B2%7D%20%2B%208w%20%2B%2016%20%20)
when we compare the given equation to ![ax^{2} + bx + c](https://tex.z-dn.net/?f=%20ax%5E%7B2%7D%20%2B%20bx%20%2B%20c%20%20)
a=1, b=8,c=16
So, ac=1*16=16 and b=8
We need factor pair of ac, 16, which sum upto b, 8.
As, 4*4=16 and 4+4=8
4 and 4 are required factor pair.

![(w+4)(w+4)](https://tex.z-dn.net/?f=%20%28w%2B4%29%28w%2B4%29%20%20)
![(w+4)^{2}](https://tex.z-dn.net/?f=%20%28w%2B4%29%5E%7B2%7D%20%20)
So,

a=3, b=10,c=7
So, ac=3*7=21 and b=10
We need factor pair of ac, 21, which sum upto b, 10.
As, 3*7=21 and 3+7=10
3 and 7 are required factor pair.
![3y^{2} + 3y+7y + 7](https://tex.z-dn.net/?f=%203y%5E%7B2%7D%20%2B%203y%2B7y%20%2B%207%20%20)

Step-by-step explanation:
hope this helped!
Hello,
This problem can be simply solved by putting everything into fractions. Since there's a total of 50 shirts but 35 of them are medium sized then the fraction would be 35/50. You're trying to find the percentage so the 2nd fraction would be out of 100 so it would be ?/100.
35 ?
---- = ----
50 100
Now you diagonal multiplication then downwards division.
100 x 35=3500
3500/50=70
So your answer is 70%!! :D
Hope this helps a bunch!!!
