Question

The length of a rectangle is 3 more than 4 times its width. The perimeter of the rectangle is 86 inches.

Answer 1

what is the length of the rectangle

Answer 2

...

Answer 3

so, we don't know the width of the rectangle, so we can call that x. Then, the length of the rectangle we don't know either, but it tells us that its 3 more than 4 times the width. Therefore, we can write it in an equation as 4x+3 (4 times the width, which is x, plus 3). Then, you would have to use those equations to set up another equation to solve for what x would be. Since the perimeter of that rectangle is 86, we can use that to set up our equation. If the sides of a rectangle added up is the perimeter, we can create an equation by saying (4x+3) + (4x+3) + x + x = 86. Then you'd simplify, and then solve for x, which should come out to be 8. Then you'd plug that into the original equation for the length (4x+3) and that should give you the length of your rectangle :)
