Write an algebraic expression that represents the surface area of a box whose width is 7y, the height is 5y and the length is 8y + 5. SA = 2(L)(W) + 2(L)(H) + 2(W)(H), where L is the length, W is the width, and H is the height of the box. Find the dimensions of the box if the surface area is 2718 m2.

For a science project, a high school research team conducted a survey of local air temperatures. based on the results of the survey, the found that the average temperatures were around 10 degrees higher than expected. this result was wrong. the trouble with the survey was that most of the locations were exposed to direct sunlight and located over asphalt or sand, which resulted in higher temperatures than normal. this is a classic example of an error in which phase of inferential statistics?
