Answer:
D
Step-by-step explanation:
Expand factors using FOIL
A
(x + 1)² - x² = x² + 2x + 1 - x² = 2x + 1 ≠ 1 ← False
B
(5x - 2)² + 4 = 25x² - 20x + 4 + 4 = 25x² - 20x + 8 ≠ 25x² - 20x ← False
C
(x + 2y)(x - 2y) = x² - 4y² ≠ x² + 4xy - 4y² ← False
D
(2x + y)(- y - 2x) = - 2xy - 4x² - y² - 2xy = - 4x² - y² - 4xy ← True
Answer: It represents decay.
Step-by-step explanation:
Because 0.5 is less than 1, it is constantly decaying because multiplying by a fraction of a number gives you less than what you started with.
