Question 491386: A board game is played on a rectangular board whose area is 96 square inches. If the length is 4 inches longer than the width find its demension.
what ive got so far:
L=w+4
L*W=96
(W)*(W+4)=96
Wsquared+4W=96

A board game is played on a rectangular board whose area is 96 square inches. If the length is 4 inches longer than the width find its demension.
what ive got so far:
L=w+4
L*W=96
(W)*(W+4)=96
Wsquared+4W=96
----------------
W%5E2+%2B+4W+-+96+=+0
(W + 12)(W - 8) = 0
W = 8
--------
If you factor 96 = 8*12 sooner, you save a lot of steps.
