Question 1101947
--------------------------------------
rectangle has a length of 27 inches less than 5 times its width.
-------------------------------------


Dimensions 5w-27 and w



--------------------------------------------------------
area of the rectangle is 3690 square inches, find the length
--------------------------------------------------------


{{{w(5w-27)=3690}}}



SOLVE FOR w
{{{5w^2-27w-3690=0}}}
-
discriminant {{{27^2+4*5*3690=74529=273^2}}};
-
{{{w=(27+273)/(2*5)}}}
{{{highlight(w=30)}}}



{{{5w-27=highlight(highlight(123))}}}---------length
