# Olga drew the regular figure shown here. She painted part of the figure a light color and part of it a darker color. She left the rest of the figure white. Which of the following equations best models the part of the figure Olga left white?

Question:

A
$3525_w128_h37.png$

Explaination

To answer this question, notice that this figure is a regular hexagon, having 6 equal sides and angles. The part painted darker can be represented by $1335_w19_h37.png$. The part painted lighter is clearly $7751_w9_h37.png$, which is equivalent to $5778_w9_h37.png$. The whole figure is represented by the number 1. So, 1 minus $1335_w19_h37.png$ minus $5778_w9_h37.png$ equals which is equivalent to $3366_w9_h37.png$. Therefore, the equation, $3525_w128_h37.png$ best models the part of the figure Olga left white.
