Answer:
Step-by-step explanation:
<u>Let's complete the square first:</u>
- p⁴ - 2p²x² + x⁴ + x =
- p⁴ + 2p²x² + x⁴ - 4p²x² + x =
- (p² + x²)² - (4p²x² - x)
<u>In order the expression above to be a perfect square, we need:</u>
<u>Solve it for x:</u>
- 4p²x² = x
- 4p²x = 1
- x = 1/(4p²)
Correct choice is d
Answer: 1.55 and 0.65 in order
Step-by-step explanation:
6.19 / 4 = 1.55 and that is in the first box
4 / 6.19 = 0.65 and that is in the second box
So, I converted the grams to kilograms, and the smallest cat was the Canada Lynx, being 15.9kg and the largest cat was the mountain lion, which was 85kg. So since it asks for the difference, we subtract.
85-15.9=69.1
Therefore the answer is B. 69.1kg
