The answer is <span>16x2 − 8x + 1

To be a perfect square trinomial, the rule must be used:
(a - b)² = a² - 2ab + b²
Let's check all choices
A. a = 7x, b = 4
(7x - 4)² = 49x² - 56x + 16
B. a = 2a, b = 5
(2a - 5)² = 4a² - 20a + 25
C. a = 5b, b = √10
(5b - √10)² = 25b² - 10√10 b + 10
D. a = 4x, b = 1
(4x - 1)² = 16x² - 8x + 1
CORRECT
It would take 5 yrs. for both trees to be the same height.
I’m pretty sure it’s n=-5
Hope this helps have a great day
Answer:
d
