I do believe that Ben's statement is always true because of the fact that when you divide a positive by a negative, or a negative by a positive, it will always equal a negative. For the equation 5.4/-6.8 the answer is -0.79411764705. And the equation -6.8/5.4 is equal to -1.25925925926. It will always equal to less then zero, except when you divide by zero.
Got you. So we will use the basic formula for the area of a rectangle and insert variable values. (^_^)
Area= Width(Height) ----------- Insert values of width and height [width = (x-1)
, height = (x+9)]
Area= (x-1)(x+9) ) -------------- Then expand if needed?
= x² +8x -9
