User: State the assumption needed to begin an indirect proof of: Parallel lines do not intersect.

Weegy: The correct answer is D. An indirect proof of the fact would go something like this: Assume that it is possible for parallel lines to intersect. In other words, assume that there exists a real solution to the following system: y = mx + b y = mx + [ c Note that the slopes of these lines, m, are the same by the definition of a parallel line. Let the y intercepts b and c be such that b ? c (in order to ensure that the two lines are not identical.) Solving this system by setting the two equations equal: mx + b = mx + c b = c This violates our premise that there must be a solution to the system (since b ? c), and the only questionable assumption was the original assumption that parallel lines intersect. Thus they do not intersect, except in the exceptional case that they are the same line, in which case they intersect an infinite amount of times.

User: Given kite ABCD. BE = 3, AE = 4 and AC = 12. Find AB

Weegy: Given kite ABCD. BE = 3, AE = 4 and AC = 12. Find AB AB = 7 [http://answers.yahoo.com/question/index?qid=20110607063058AAOW04J]

User: Given kite ABCD. EB = 2x + 4 and BD = 5x + 1. Find the value of x

Weegy: Hi, If ED is measuring across the long diagonal, then EB = ½BD 2x+ 4 = ½(5x+1) 2x+ 4= 2.5x + .5 3.5 = .5x 7 = x I hope that helps!! :-) [http://answers.yahoo.com/question/?qid=20071026151940AAClfhU]

User: given EF is the midsegment of Isosceles trapezoid ABCD. BC = 17x, EF = 22.5x + 9 and AD = 30x + 12, find x

Weegy: AD should be 30x. it's already given. if you want to find x the solution will be :The midsegment (or median) in an isosocles trapezoid is half the sum of the lengths. 2(22.5x+9)=17x+30x+12 45x+18=47x+12 18-12=47x-45x 6=2x *x=3

User: Given Isosceles trapezoid ABCD. AB = 3x - 4 and CD = x + 12. Find AB

Weegy: (3x-2) squared is 9x^2 - 12x + 4.

User: 9x^2 - 12x + 4

Weegy: 9x^2 - 12x + 4 = 9x^2-6x-6x+4 3x(3x-2)-2(3x-2) (3x-2)(3x-2)

User: 9x^2-6x-6x+4 3x(3x-2)-2(3x-2) (3x-2)(3x-2)
