That will depend on what type of quadrilateral it is and other information such as its area.

Yes. Since they are rational numbers, let's call the first one a/b and the second one c/d where a,b,c, and d are integers. Now we can subtract by finding a common denominator. Let's use bd. So we have ad/bd-cb/bc= (ad-bc)/CD which is rational since we know ad and bc are integers being the product of integers and CD is also an integers. Call ad-bd=P and call CD=Q where P and Q are integers. We now see the difference is of two rationals is rational.
The GCF is 27b.

Double-replacement
When many were taught chemistry in the 1970s this was called a double decomposition reaction. It is now called a salt metathesis reaction and also double displacement reaction. There are examples and more information at the related link.
This kind of chemical reaction is usually called "displacement" and sometimes "substitution".
The general form for a double-displacement reaction is AB + CD -> AD + CB, where two compounds swap anions or cations to form two new compounds.
If BC=4.5,CD=,7.7,and AD=16.7. Find AB to the nearest tenth If BC=4.5,CD=,7.7,and AD=16.7. Find AB to the nearest tenth
Single replacement
The general equation for an endothermic double replacement reaction is: AB + CD → AD + CB + heat absorbed. In this reaction, the reactants AB and CD exchange ions to form the products AD and CB, with the absorption of heat from the surroundings.
a(b + d).
Double replacement
AB + CD ==> AD + CB
The general equation for a double displacement reaction is: AB + CD → AD + CB, where two compounds switch partners to form two new compounds.
That depends on the value of CD and the perimeter of the quadrilateral out lined in the question
