15 percent
Its 15 percent for the reason that I th k it’s is
Let x = length and y = width
You would have 2 lengths, so 2x and 3 widths, so 3y
Those need to equal total length of fence:
2x + 3y = 1200
The 3 widths would equal total fence minus the 2 lengths:
3Y = 1200-2x
Solve for y: y = 400 -2/3x
Area = length x width = xy. Replace y :
Area = x(400-2/3x) = 400x-2/3x^2
Differentiate:
400-4x/3 =0
4x/3 = 400
4x = 1200
X = 300
Y = 400-2/3(300) = 200
The dimension would be 300 ft x 200 ft
4x+24=84 4x=60 x=15 length =27 width = 15
D is correct.
Inputting any of the numbers under the x column into f(x) =|x| will output the number as a positive
Answer:
C
Step-by-step explanation:
you need to start by plugging in -2x+4 every were it says y then solve for x when you have found x plug it into one of the equations and solve for y
