a. Show that the system of rational expressions is closed under addition, or give an example showing the contrary.
otez555 [7]
A "rational expression" is a fraction in which the numerator and the denominator are both polynomials. The sum of two such expressions will always produce another such expression, viz., 
<span>p(x)/q(x) + r(x)/s(x) = [p(x)s(x) + q(x)r(x)] / [q(x)*s(x)]. </span>
<span>The numerator and denominator of the sum will both be polynomials when fully expanded</span>

natali 33 [55]

Answer:

36 minutes

Step-by-step explanation:

Depth of the fjord = 1308 m

Rate at which the submersible dives = 35 meters/minute

Distance to the bottom of the fjord should be 48 m

Distance the submersible has to go underwater is 1308-48=1260\ \text{m}

Time is found by dividing the distance the submersible has to go underwater by rate at which the submersible dives

\dfrac{1263}{35}=36\ \text{minutes}

The time taken by the submersible to dive the required distance is 36 minutes.
