Question 1158888
<font face="Times New Roman" size="+2">


The current area is 1200 square feet, so the new area must be 450 square feet (1200 minus 750).  So:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ (20\ -\ x)(60\ -\ 6x)\ =\ 450]


Solve the quadratic for *[tex \Large x] and then calculate *[tex \Large 20\ -\ x].

My calculator said it, I believe it, that settles it
