Remember your lemonade stand? Your new improved recipe is selling even better than the last recipe! Your new earnings, y (in cents), when you charge x cents per glass, are given by the equation y = 150x-x^2 What is the maximum amount you can earn? Show your thinking.​

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )

the answer is a. 72. but i cant answer with less than 20 characters so here's some random text talking about it.

question

given the diagram below, what is md?

the sum of the interior angles is 360°

take away from 360 the sum of the knows angles and you will have the angle d.

360 - 108 - 108 - 72 = 72°
