Answer:
The dimensions are 25 * 50 feet.
Step-by-step explanation:
The 3 sides of the pen will measure (2x + y) feet where x is the width and y is the length.
2x + y = 100
y = 100 - 2x
The area A = xy = x(100 - 2x) ft^2.
Finding the maximum area.
A = x(100 - 2x)
A = 100x - 2x^2 Finding the derivative:
A' = 100 - 4x
For maximum value of A this equals zero:
100 - 4x = 0
4x = 100
x = 25 ft, so this is the width.
The length is 100 - 2(25) = 50 ft.
Answer:
Step-by-step explanation:
2x + 3y = 12
subtract 2x from both sides
3y = -2x + 12
divide both sides by 3
y = -2/3x + 4

Answer:
x= -1 and -2
Step-by-step explanation:
5x + 9 < 7
5x < -2
x < -.04
the only integers 5 can be multiplied by to get a number less than -.04, greater than or equal to -2, and less than or equal to 5 are -1 and -2
Answer:
(a) The grass is not green.
(b) Nothing can be concluded about squirrels.
Step-by-step explanation:
(a) If squirrels cannot fly, then the you can conclude that the grass is not green, because if the grass was green, then squirrels would be able to fly.
(b) By discovering that the grass is not green, nothing can be concluded regarding squirrels. The statement says that squirrels can fly if the grass is green which doesn't necessarily mean that they can't fly if the grass is not green.
