PLEASE ANSWER THIS FASTJoseph is given the formula for the perimeter of a rectangle. The first step in solving for the variable L in the equation P = 2L + 2W is to: add the 2W to both sides of the equal sign. subtract the 2W to both sides of the equal sign. divide the 2 to both sides of the equal sign. None of these choices are correct.

Recall that the owner of a local health food store recently started a new ad campaign to attract more business and wants to know if average daily sales have increased. historically average daily sales were approximately $2,700. the upper bound of the 95% range of likely sample means for this one-sided test is approximately $2,843.44. if the owner took a random sample of forty-five days and found that daily average sales were now $2,984, what can she conclude at the 95% confidence level?
