Factorise the following 10x a – 20 36m a + 27b + 9c 9y² - 12y 30ab³ + 35a²b 24x4y³ - 40x²y

Expand and simplify the following
(x + 7)(x + 5) (x - 4)(x + 5) (3x - 2)(x - 6) (2x + 1)(5x - 2) (x + 7)² (4x + 3)²

Factorise the following
x² + 8x + 6 x² - 7x + 12 x² - 2x - 35 x² + x + 56 x² - 49 x² - 121

Solve 4x+2=3x+12 10x-3=5x+27 3x - 6 = 10 – x 6x + 2 = x 5(2x + 3) = 8x + 23 x² + 15x + 26 = 0 x² + 2x - 24 = 0 x² - 81 = 0

a) Write an expression for the perimeter of the shape
a) Write an expression for the perimeter of the shape. b) The perimeter of the shape is 23cm. Calculate the value of x. 3x+2 5x-3 4x x + 12
