What is the area of a parallelogram that has a base of 12 3/4 in and height of 2 1/2

Figure lmno is located at l (1, 1), m (4, 4), n (7, 1), and o (4, −2). use coordinate geometry to best classify quadrilateral lmno.

The vertices of a triangle are a(7.5), b(4,2), and c19. 2). what is

Use mathematical induction to prove the statement is true for all positive integers n, or show why it is false. 1^2 + 4^2 + 7^2 + + (3n - 2)^2 = [n(6n^2-3n-1)/2]
