Write and simplify an algebraic expression for the rectangle with sides of 2x and 6x-1

Name the most appropriate metric unit for each measurement like the mass of cow

Lines b and c are parallel. what is the measure of 2? m2 = 31° m2 = 50° m2 = 120° m2 = 130°

What is the value of the discriminant of the quadratic equation -2x = -8x + 8 and what does its value mean about thenumber of real number solutions the equation has?
