The first derivative is 5
P = 2 x ( W+L)
P = 2 x (W + 2W)
p = 2 x 3W
P = 2 x 3(20/3) =40
1/7 x 9/4 = 9/28
This process to solving division involving fractions is called “keep, change, flip”
Answer A seems to make the most sense to me<span />
The system of Roman numerals is based on using special symbols to denote decimal digits I=1, X=10, C=100, M=1000, and their halves V=5, L=50, D=500. Positive integers are written by repeating these numerals.
