Answer:
Option D. It's a perfect square trinomial.
Step-by-step explanation:
(a) 36x² - 4x + 16
= (6x)² - 2(2x) + (4)²
It's not a perfect square trinomial
(b) 16x² - 8x + 36
= (4x)² - 2x(4x) + (6)²
It's not a perfect square trinomial
(c) 25x² + 9x + 4
= (5x)² + 2 + (2)²
It's not a perfect square trinomial
(d) 4x² + 20x + 25
= (2x)² + 2(10x) + (5)²
= (2x+5)²
It's a perfect square trinomial.
Answer: $42042.50
Step-by-step explanation:
We need to use algebra and equations.
A = P x (1 + (R/n)/100)^nt
our amount (A) is $72K
the number of times we compound the money (n) is 12 (12 months in a year, 'compounded monthly')
our rate (R) is 9 (9%)
our time (t) is 6 (6 years)
we need to find our principal/initial amount (p)
72000 = p x (1 + 0.0075)^12x6
p = $42042.50
209/2 is 104.5, add 0.5 to once and take away 0,5 once so your left with 104 and 105 then 104+105=209 and they’re integers which are consecutive. :))
