+25 Bob is building a rectangular building to store equipment. He decided to make the length (4x-1) and the width (x+2). Show that the fraction of length over width can be expressed as 4- 9/x+2
+128474 [ 4x - 1 ] / [ x + 2] =
[4x + 8 - 9 ] / [x + 2] = [split into separate fractions ]
[4x + 8] / [x + 2] - 9/ [x +2] =
4[x + 2] / [x + 2] - 9/ [ x + 2] =
4 - 9/ [x + 2]
