The area if a rectangle is 48 square centimeters. the lenght of the rectangle is 8 centimitwrs longer than the witch. which equation modles this situation

So, The length is 8 cm longer than the width.

Area of a rectangle = l *w

48 cm^2 = l *w

l = w+8

48 cm^2 = w * w+8

48 = w^2 +8w

^ that's the equation that models it.  Or any other one listed

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
