Alejandra was given this problem to solve her math classz x ^ 2 + 9 = 0. She realized that both x ^ 2 and 9 are perfect squares . Therefore Alejandra chose to use difference of squares and completed the problem as such. (x + 3)(x - 3) = 0 x = - 3 and x = 3 Explain why Alejandra was incorrect in choosing to use the difference of squares method. (Explain why she could not use the difference of square method x ^ 2 + 9 = 0)

You drop a rubber ball off the roof of a 50 meter high building onto a paved parking lot. it bounces back up with every bounce, but not quite all the way back up to you. after the first bounce it bounces back only 80 percent of the distance it was dropped from. the pattern continues, meaning after every bounce it comes up to just 80 percent of the previous maximum height. so if before the first bounce the height is 50 meters, what height does the ball reach after the fifth bounce? round your answer to one decimal place and chose the correct response from the choices below:
