Suppose the lengths of the four side of a quadrilateral are represented by the expressions 3a, a+2, 2a-1, and 3a+6. write the sum of the lenghts (the perimeter), and then simplify.

how do u find the area of a quadrilateral?

use factoring and the zero-product property to solve 4a^2-11a+6=0 9r^2-30r+21=-4

No

subtract 8 from 3 then add two to that answerthen divide by 3. then u will get x
