Explanation:
There are many versions of the taxonomy diagram for quadrilaterals. The details depend on the particulars of the definitions you use. Here, we'll say a parallelogram is a subset of trapezoids. Not all authors would agree.
(2) kite -- two pairs of adjacent same-length sides
(3) trapezoid -- (at least one) pair of parallel opposite sides
(4) parallelogram -- opposite sides are parallel
(5) rhombus -- all sides the same length (and opposite sides parallel)
(6) rectangle -- parallel opposite sides and right angles
(7) square -- same-length parallel opposite sides and right angles
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>
