How do i solve (x+2)^2 with given identity? my teacher wants me to show how to solve it using multiplication and given i know how to solve it with foil and i get the answer and show it like this foil: (x+2)^2 (x+2)(x+2) x^2+2x+2x+4 x^2+4x+4 but given identity i don't know pls i've been trying to figure it out for hours

This assignment is past the original due date o this data is from a sample. calculate the mean, standard deviation, and variance 16.7 11.1 46.7 14.8 13.3 16.6 18.5 47.3 42,8 show the following answers to 2 decimal places. sample mean- sample standard deviation ( use the standard deviation above for your calculation.) sample variance ooops- now you discover that the data was actually from a population! so now you must give the population standard deviation.
