LM¯¯¯¯¯¯¯ is the midsegment of trapezoid ABCD. AB = 78 and DC 142. What is LM? The image is of a regular trapezoid ABCD with base DC. L and M are marked at mid points of side AD and BC respectively which are joined with a segment. A. 64 B. 110 C. 120 D. 220

Use the x-intercept method to find all real solutions of the equation. -9x^3-7x^2-96x+36=3x^3+x^2-3x+8

What is the sum of the first 8 terms of the geometric series

Look at this system of equations. -3x + 3y = 12 y = x + 4 the solution set of this system is best explained by which of these statements? a) the graphs of the equations are the same line because the equations have the same slope and the same y-intercept. the system has infinitely many solutions. b) the graphs of the equations are parallel lines because they have the same slope but different y-intercepts. the system has no solution. c) the graphs of the equations are lines that intersect at one point because the equations have the same slope but different y-intercepts. the system has exactly one solution. d) the graphs of the equations are lines that intersect at one point because the equations have the same slope and the same y-intercept. the system has exactly one solution.
