Solution Summary
This solution contains an attached file that solves the following problems:
1.What are the dimensions of a box constructed of 150 square centimeters that will produce the largest volume possible?
2.compute the difference quotient for f(x)=1/x
3.Solve (3x^2-8x -3 ) /(x^2-4x+4) >=0
4.)Sole 7^(2x^2+3x)=49^(6-x) without using logarithms.

1.) D this volume is 927cm^3
1.D A was 797
1.DI B was 797
1.DII C was 714
1.DIII E was 737
Simply solved by computing volumes of the choices presented and choosing the largest volume.
2 (1/(x-h)-1/x)/h= 1/(xh-h^2)-1/xh = -h^2/( (xh)^2-xh^3) = -1/(x^2-xh)
3 Since h ->0, the final answer is 1/x^2
1.D is the correct ...
