(HELP PLEASE) The Converse of the Pythagorean Theorem states that: (chose one) A. if a2+b2=c2, then the triangle is a right triangle.
B. if a2+b2=c2, then the triangle is not a right triangle.
C. if the triangle is not a right triangle, then a2+b2≠c2.
D. if the triangle is a right triangle, then a2+b2=c2

30 determine the coefficient on x 12 y 24 x12y24 in ( x 3 + 2 x y 2 + y + 3 ) 18 . (x3+2xy2+y+3)18. (be careful, as x x and y y now appear in multiple terms! )
