However note that this is not a normal factoring problem as dimensions must be greater than zero, so x>2
Since we were not given a specific volume there are infinite solutions provided x>2
Answer:StepThe length of a rectangle is 4 cm more than 3 times its width. if the area of the rectangle is 15 sq cm, find the width whats the work Let width be W Then length = 3W + 4 With area being 15 sq cm, we get: W(3W + 4) = 15 3W - 5 = 0 OR W + 3 = 0 3W = 5 OR W = - 3 (ignore) Width, or , or cm-by-step explanation:
