Answer:
First box: x4 - 2x2y2 + y4
Second box: 2x4 - 2x2y2 + 2y4
Third box: 2(x4 - x2y2 + y4)
<h3>hope it's help you </h3><h3>plz mark as brain list ......!!!!!!!!!!!!</h3>
Well 3 x 8 = 24 + 7 = 31 so 31/8
increasing 20 to 40 is the same as increasing 20 by 20 (or itself), so it is a 100% increase. Decreasing 40 to 20 is the same as decreasing 40 by 1/2 or by 20. So it is a 50% increase.
when going from 20 to 40, the number is being doubled, and when youre going from 40 to 20 you are cutting the number in half.
hope this helped:)
