You know x, so just plug it in for the answers. Like AB = x + 7, so since x is 3, then AB is 3 + 7 = 10
BD is 2x + 3x -1 = 6 + 9 - 1 = 14
CE is 3x - 1+ 2x + 3 = 9-1+6+3= 17

Step-by-step explanation:

$x=\frac{-(-9)\pm\sqrt{(-9)^2-4(2)(4)} }{2 \times 2} \\x=\frac{9\pm\sqrt{81-32} }{4} \\x=\frac{9\pm\sqrt{49} }{4} \\x=\frac{9 \pm 7}{4} \\either~x=\frac{9+7}{4} =\frac{16}{4} =4\\or\\x=\frac{9-7}{4} =\frac{2}{4} =\frac{1}{2}$
