HELP ASAP I WILL GIVE BRAINLIST Is the set of rational expressions closed under ​subtraction​? Explain p(x) - r(x) =
q(x) s(x)

[1] YES. If q(x) and s(x) is not zero, then the rational expressions is closed under subtraction. The numerator is formed by multiplying and adding integers wherein the denominator is also an integer. If functions are subtracted, then it will yield an integer thus is a rational expression.

2^y = ln 5, or   y(ln 2) = ln 5.   solving for y,   y = (ln 5) / (ln 2).   y=5

step-by-step explanation:

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
