Yun was trying to factor 724 – 142. He found that the greatest common factor of these terms was 7 and
made an area model:
Width
72
72
7
-142
-142
What is the width of Yun's area model?
Width =

Consider the following equation. 1/2x^3+x-7=-3sqrtx-1 approximate the solution to the equation using three iterations of successive approximation. use the graph below as a starting point. a. b. c. d.
