1 ) Identify the information given in the question:Total number of cupcakes bought: 125Number bought by Emma is 50% more than Robin: mathematically we write that was Emma = 1.5 Robin as 50% = 0.5 in decim...

Apply FOIL (First, outside, inside, last): (x + 4)(x - 5) = x² - 5x + 4x -20 = x² - x -20 x(x + 4)(x - 5) = x( x² - x -20 ) = x³ - x²- 20x

To see if (0,8) lies on the line y, substitute 0 (the x coordinate) into y = 4x+9 so y=4(0)+9 y=4(0)+9 therefore y= 0+9 = 9since the output (9) is not the same as the respective coordinate (8), (0,8) d...

The question asks for the roots, this simply means the numbers that could replace x in the equation and the result = 0. There are two ways too do this, firstly either using the Quadratic formula, or my fa...

For example x² - 2x - 35 = 0You would have two approaches to this question. You can either use the quadratic formula or you could simplify the expression. Using the formula you would have x = (...
