Answer:
11+ 200% = 33 pounds
The percent increase is 200%
Step-by-step explanation:
To figure this out, you should think about the multiples of 10 boxes you could have.
If I had 10 small boxes, there would need to be 86 large boxes. 86 is not evenly divisible by 8 so that doesn't work.
If I had 20 small boxes, there would be 76 large boxes. 76 is not evenly divisible by 8.
If I had 30 small boxes, there would be 66 large boxes. 66 is not evenly divisible by 8.
If I had 40 small boxes, there would be 56 large boxes. 56 is every divisible by 8.
4 cartons of 10 small boxes and 7 cartons of 8 large boxes would be needed. This is a total of 11 cartons.
First factor out 2
2(x^4 - y^4)
Rewrite it as ((x^2)^2) and ((y^2)^2)
Then you get..
2 ((x^2)^2) - (y^2)^2))
Now both terms are perfect squares, factor using the difference of squares formula, a^2 + b^2 = (a+b)(a-b)
a= x^2 and b= y^2
2((x^2 + y^2)(x+y)(x-y))
clean it up!
2(x^2 + y^2)(x+y)(x-y)
