Question

The dimensions of a rectangle are 3x + 4 and 4x – 1. Which expression best represents the perimeter of the rectangle in simplest terms?

Answer 1

`p = √((3x + 4)(4x - 1)) + (3x + 4) + (4x - 1)`


`p = \sqrt{12 {x}^(2) - 3x + 16x - 4} + (3x + 4) + (4x - 1)`


`p = \sqrt{12 {x}^(2) + 13x - 4 } + (3x + 4) + (4x - 1)`


`p=\boxed{√(12x^2+13x-4)+7x+3}`
