## anonymous one year ago The equation w(w + 6) = 40 represents the area of a rectangle where w represents the width. What are the dimensions of the rectangle?

So I guess you could do the expand thing, and solve the quadratic again :)

$$\large\rm w^2+6w-40=0$$ Do you understand how to get to this point?

yes. Distribute, subtract, then work it from there. Thanks!
