PLZ I NEED QUICK HELP!!! The perimeter of a rectangular wooden deck is 90 feet. The deck's lenght, l, is 5 feet less than 4 times its width, w. Which system of linrar equations can be used to determine the dimensions, in feet, of the wooden deck?

Respuesta :

first thing you should do is simplify the question they are asking for the parameter and you know the parameter is two times the length plus two times the width.
[tex]2l + 2w = p[/tex]
we know the only thing that is changing in this equation is the length and the perimeter
[tex]2(4w - 5) + 2w = 90 \\ l = 4w - 5[/tex]
