If Hope this helped if any question feel free to ask!! :D
<span>The answer is this 20t2 + 9t – 20. Go look up a video for foiling </span>
The number = y
2y + 1/3 = 2/3 - 3y
(add 3y to both sides)
5y + 1/3 = 2/3
(subtract 1/3 from both sides to isolate y)
5y = 1/3
(divide by 5)
y = 1/15
Answer:
n = 9
Step-by-step explanation:
Note that
256 =
, thus
= 
Since the bases on both sides are equal (2) equate the exponents
n - 1 = 8 ( add 1 to both sides )
n = 9
