Carla uses a compass and straightedge to construct perpendicular lines. Daryl uses technology to construct perpendicular lines.

2(x/8 + 3) = 7 + 1/4x what is x
malfutka [58]

Answer:

x1 = 2 -\sqrt{5}

x2= 2 +\sqrt{5}

Step-by-step explanation:

x/4 + 6 = 7 + 1/4x

(x^2 - 1)/4x = 1

x^2 - 1 = 4x

x^2 - 4x -1 = 0

x= (4+\sqrt{20})/2 = 2 -\sqrt{5}

x= 2 +\sqrt{5}
