Answer:
x =(18+√-64)/2=9+4i= 9.0000+4.0000i
or:
x =(18-√-64)/2=9-4i= 9.0000-4.0000i
Step-by-step explanation:
Algebraic equations include "variable" which are unknowns that you have to solve the equation to find out their value
I think 1, because you need age for receive that document
Since p=24 and to get p you do 3w+3w+w+w which equals 8w=24 and 24/8 is 3 so your answer is 3
Let the length of the north and south sides be x, then the length of the east and west side is 32/x.
The total fencing needed is the perimeter of the rectangle = 2x + 2(32/x) = 2x + 64/x
Cost of fencing the north and south sides is 2(2x) = 4x
Cost of fencing the east and west sides is 4(64/x) = 256/x
Total cost (C(x)) of fencing the vegetable patch is 4x + 256/x
For minimum cost dC/dx = 0
4 - 256/x^2 = 0
4x^2 - 256 = 0
x^2 = 64
x = 8
Therefore, the <span>dimensions of the vegetable patch with the least expensive fence is
</span><span>north and south sides = 8 ft
</span><span>east and west sides = 32/8 = 4 ft</span>
