Answer:

D. x = 1.7 or x = 5.7

Explanation:

The left side of the equation is graphed in blue. The right side of the equation is graphed in red.

The solution of the equation is the x (and y) that make both equations true.

On the graph these solutions are the points where the two graphs intersect.

Those two points have x values that are positive (and y's that are negative) Only answer D. has x-values that correspond to the x-values of the points of intersection.
