Find the product of (2x + 5y)2.
4x2 + 20xy + 25y2
4x2 − 20xy + 25y2
4x2 − 25y2
4x2 + 25y2

Suppose you want just guess at the answers in a 5 question multiple-choice test. each question has 3 responses and only one is correct. what is the probability of getting two questions right just guessing? 20 points 0.3275 0.2753 0.7532 none of the above

What are the solutions of the system? solve by graphing. y = -x^2 - 3x + 2 y = -2x + 2

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.
