Answer:
Step-by-step explanation:
Perimeter of a garden = 2(L+W)
Area of the gerden = LW
L is the length
W is the width
Given
Perimeter = 155ft
Area = 1400ft²
Substitute
1400 = LW
155 = 2L+2W
from 1;
W = 1400/L
Substitute into 2;
155 = 2L + 2(1400/L)
155 = 2L + 2800/L
155L = 2L² + 2800
2L²-155L + 2800 = 0
Factorize
L = 155±√155²-4(2)(2800)/4
L = 155±√24025-22400/4
L = 155±√1625/4
L = L = 155±40.31/4
L = 194.31/4
L = 48.82 feet and;
L = 155-40.31/4
L = 28.67ft
Hence the approximate length of the garden is at least 28.67 feet and at most 48.82 feet.
Some multiples are 24, 48,96
Answer:
Ok ive done that too, but my answer was B.
Step-by-step explanation:
Answer:
20
Step-by-step explanation:
6² + 19² = c²
36 + 361 = 397
√(397 = 19.9248588452 ≈ 20
my answer is based in the assumption that you are trying to find the hypotenuse.
Hope this helps! (:
Is 6/2(2+1) 1 or 9? I will tell you why it should be one:
6/2a = 3/a. Let a = 2+1.
