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:
(b) 23
Step-by-step explanation:
The diagonals of a rectangle are the same length, so ...
AC = BD
2x +10 = 56
x +5 = 28 . . . . . divide by 2
x = 23 . . . . . . . . subtract 5
Divide both the numerator and denominator by the gcf, which is 3.
3/3=1
6/3=2
Final answer: 1/2
The problem is:
We now do L.C.M. of numerator and add, also do L.C.M. of denominator and add together:
Dividing by a fraction is same as multiplying by its reciprocal, so we have:
x cancels out, so can multiply and write:
This is the simplified form.
