What is the perimeter of a rectangular building that is 80 feet wide and 140 feet deep?

Let f(x) = 3 − x . find the average rate of change of f(x) from x = a to x = a + h and simplify your answer so that no single factor of h is left in the denominator.

Solve for x and y: 217x + 131y = 913; 131x + 217y = 827
