Photos A, B, and C are all square photos. The area of Photo C is the same as that of a rectangular photo whose length is the side length of photo A and whose width is the side length of photo B. Use the properties of rational exponents to write and solve an equation to find the side length of photo A. Photo A - Area=x cm^2
Photo B - Area=72 cm^2
Photo C - Area=110 cm^2

Ahypothesis is: a the average squared deviations about the mean of a distribution of values b) an empirically testable statement that is an unproven supposition developed in order to explain phenomena a statement that asserts the status quo; that is, any change from what has been c) thought to be true is due to random sampling order da statement that is the opposite of the null hypothesis e) the error made by rejecting the null hypothesis when it is true
