The sum of all interior angles of a quadrilateral is always 360
A parallelogram is a quadrilateral, so the answer is 360 degree so
Hey, I really want to help you but I am going to need a clearer idea of the problem. You need more signs in there (addition, subtraction, multiplication, and/or division)
Answer:
Hey there!
4a^2-20a+25 can be factored to (2a-5)(2a-5). Thus, the side length of the square is 2a-5. Basically, we want to find two of the same binomials that can multiply to get 4a^2-20a+25. For example, 2a times 2a = 4a^2, and you can use the foil method to solve for the rest.
4a^2 - 20a +25
(2a)^2 - 20a + (-5)^2
(2a - 5)^2
(9a2 − 16b2) is just a difference of squares, and can be factored to (3a+4b) and (3a-4b). The difference of squares formula can give us this.
Let me know if this helps :)
