Answer:
2(2n² + 2n) + 1
Step-by-step explanation:
(2n + 1)² can also written as
(2n + 1) × (2n + 1)
= 4n² + 2n + 2n + 1
= 4n² + 4n + 1
= 2(2n² + 2n) + 1
= an odd

A plane 2-dimensional figure with three straight sides and three angles.
2 ways
1 calcluls
2. algebra
calculus, just take the deritivive and find wher it is 0
y=-0.2x+10
at x=50
sub 50 for x in original
y=250
algebra
for
y=a(x-h)²+k
(h,k) is vertex
k is maximum value
complete the square
y=(-0.1x²+10x)
y=-0.1(x²-100x)
take 1/2 of -100 and square it and add negative and positive inside
-100/2=-50, (-50)²=2500
y=-0.1(x²-100x+2500-2500)
factor perfect square
y=-0.1((x-50)²-2500)
exand
y=-0.1(x-50)²+250
vertex at (50,250)
producing 50 units yeilds a sale price of $250
max price is $250
