I need homework help!
we have to write the equation and solve for x. The area is 42, the width is x+1 and the length is x please help!!
6 is length 7 is width :) hope you understand
Well, the area is length * width, so if it's 42, I guess the answer would be 20+1. 21*2=42-------edit-------I was on my phone and didn't see all of it. I don't think this logic works anymore, it's already solved so... yea...
A = l * w, so 42 = (x) (x + 1) is the equation you have to solve
x(x+1)=42. x^2+x-42=0. It's quadratic, so factor it and set each factor equal to zero.
