Rearrange x + y = 11.
x = 11 - y
Substitute into other equation.
4(11 - y)^2 = 3y^2 = 8
Answer:
4(11 - y)^2 - 3y^2 = 8 (#2)
Where’s the actual question??
Answer:
A. Wednesday is the correct answer
Answer:
Dimensions are
Length = 42.4264 feet
Width = 42.4264 feet
Step-by-step explanation:
Let the length be L and width be B
Data provided in the question:
Area of barn = LB = 1800 square feet
or
L = [ 1800 ÷ B ] feet
Amount of fencing = Perimeter of the barn, P = 2( L + B)
P =
differentiating the P with respect to B
we get,
for point of maxima or minima
or
or
B² = 1800
or
B = 42.4264 feet
on again differentiating
here,
positive value mean at B = 42.43 feet perimeter is least
Therefore,
L = 1800 ÷ 42.426
= 42.4264 feet
Hence,
Dimensions are
Length = 42.4264 feet
Width = 42.4264 feet
We have a fraction of two integers, so 25/9 is rational. A rational number is any fraction of two integers (as long as the denominator is not zero).
