Solve the following quadratic inequality: 6x^2 -x -35 < 0
Begin by factorisation: (3x+7)(2x-5) < 0 Then determine which values of x give 0 -7/3 and 5/2Draw a sketch of the graph Y intercept = -35Then determine where less than 0 - under x axis. Reach -7/3<x<5/2

The rectangles A and B have perimeters of 94cm and 56cm as shown below (insert diagram). Rectangle A: base = 2x cm, height = 3y cm. Rectangle B: base = (x+6)cm, height = (y+4)cm. Use an algebraic method to calculate the area of each rectangle. (8 marks)
solve: [(3x-2)/4] - [(2x+5)/3] = [(1-x)/6]
