C, or the last photo, shows a reflection.
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>
Answer:
nope sry. so yeah my answer has to "fully load"
Step-by-step explanation:
let x = the price of a book
so you would have
