Answer:
Step-by-step
i) a² - 2ab + b² = (a + b)²
a² = p² ; a = p
b² = 16 = 4² ; b = 4
2ab = 2*p*4 = 8p
p² - 8p + 16 = (p - 4)²
ii) a² + 2ab + b² = (a +b)²
a² = 121x² = (11x)² ; b² = 4y² = (2y)²
2ab = 2 * 11x * 2y = 44xy
121x² + 44xy + 4y² = (11x + 2y)²

A) In 1st Figure, Blue boxes means unit of diet soda = 8
Green boxed is regular sods = 4
Total Boxes = 12
Value of 1 Box = 888/12 = 74
Now, We know, we have 74 soda in each box, and 8 boxes of diet soda, so the number of diet soda = 74 * 8 = 592
In short, Your Answer would be: 592B.) Now, In 2nd figure, You can see
Red boxes mean Short sleeve short which is = 3
Green means Long sleeve = 7
Total Boxes = 10
Value of 1 Box = 460/10 = 46
Now, we know we have 46 shirts in each boxes and their is 3 boxes of short sleeves.
So, Number of Short sleeves = 46 * 3 = 138
In short, Your Answer would be: 138Hope this helps!
