The first step that should be taken in solving the inequality 4(3-5x)>-6x+9 is multiplying the number before the parenthesis. T<span>he part of the expression within the </span>parentheses<span>, is evaluated first, so the first step is to multiply 4 with that what's in the the parenthesis. We will obtain the following inequality: 4*3-4*5*x></span><span>-6x+9 12-20x>-6x+9</span>
( y - 4 ) ( y² + 4 y + 16 ) = y³ + 4 y² + 16 y - 4 y² - 16 y - 64 The result is a polynomial of the form: y³ + 4 y² + a y - 4 y² - a y + 64; Answer: a = 16
