Polygon ABCD is translated to create polygon A B'CD'. Point A is located at (1.51, and point is located at (-2, 1). What is the disance from B to B'?

b is the right answer

x=25tan30=14.43 or the answer is b

josh is incorrect

x= 7 and x= -1

step 2 is wrong and honestly first step is not needed, you just need to figure out the factors

i know its wrong because if you plug in the solutions josh found, they do not work (in the original equation)

x^2 -6x -7 = 0

(x-7) (x+1) = 0

x-7=0 x+1=0

x= 7 x= -1
