Make an inference I sit in my seat, as a lady at the piano plays a soft melody. Each chair in the auditorium is decorated with w
hite flowers. Everyone is wearing pretty clothes with lace and silk. I am wearing a puffy pink dress. The lady at the piano plays a new song. Everyone stands, and the back doors of the auditorium open. The bride steps inside. Where am I?
P = 2w + 2l where w is the width, and l is the length. We know the length (l) is 3 inches longer than it's width (or l = w+3). Substitute w +3 into Perimeter equation. P = 2w + 2(w+3).
A kid has $1 and he receives $1 everyday after doing his homework. So the initial money that he has is the y-intercept and the money that he receives everyday is the slope.
