Step-by-step explanation:
f'(x) = 6x-12
in vertex : f'(x) = 0
6x-12 =0 => x=2
f(2) = 3 ( 2² ) -12 (2 ) +1 = -11
vertex ( 2 , -11 )
Answer:Behest
Step-by-step explanation:
Since it is a square each side must be equal in length so the length and width have the same measurements...
length x width=area so in this case area divided by two would equal length and width
300 divided by 2 equals 150 so each side is 150 square feet
The value of y if the perimeter of the figure is 5y is 15meters.
<h3>How to find the perimeter of a polygon?</h3>
The perimeter of a polygon is the sum of the length of the whole sides.
Therefore,
perimeter = y + 2y + 30
perimeter = 5y
Hence,
5y = 3y + 30
5y - 3y = 30
2y = 30
divide both sides by 2
2y / 2 = 30 / 2
y = 15
Therefore, the value of y is 15m.
