Let the width = x feet, then the length = 160 - x feet.
The area = x * (160 - x) = 4000
160x - x^2 = 4000
x^2 - 160x + 4000 = 0
x = [- (-160) +/- sqrt (160^2 - 3 * 1 * 4000)] / 2
x = 128.98 or 31.01
answer is length = 129 feet and width = 31 feet ( to nearest foot).
Answer:
3/68
Step-by-step explanation:
Answer:
x = -7
x = 4
Step-by-step explanation:
The greatest common factor is 2
We first have to look for the largest number that goes into both equations. The factors of 12 are 1, 2, 3, 4, 6 and 12. None of 3, 4, 6, or 12 go into 26 evenly. So 2 is the largest number you can take out.
With the variables, we take out as many as the lowest number will let us. Since the smallest number of n's is 2 in the second term, we take that many.
