Answer:
Log X vs ln x
Usually log(x) means the base 10 logarithm; it can, also be written as log10(x) . ... ln(x) means the base e logarithm; it can, also be written as loge(x) . ln(x) tells you what power you must raise e to obtain the number x. ex is its inverse.
Step-by-step explanation:
A = LW
A = 320
L = 5W
320 = W(5W)
320 = 5W^2
320/5 = W^2
64 = W^2
sqrt 64 = W
8 = W
L = 5W
L = 5(8)
L = 40
so the length (L) = 40 cm and the width (W) = 8 cm
P = 2(L + W)
P = 2(40 + 8)
P = 2(48)
P = 96 <=====
The answer would be 20 days all you have to do is multiply 10 by 2
