Given: the coordinates of iscosceles trapezoid jklm are j(-b, c), k(b, c), l(a,0), and m(-a,0).
prove: the diagonals of an isosceles trapezoid are congruent.
as part of the proof, find the length of km

a) a2+b2+c2
b) (-a+b)2+c2
c) (a+b)2+c2

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
