<span>Let's solve your equation step-by-step.
-x^2 = -36
</span><span>Step 1: Divide both sides by -1.
</span><span>-x^2/-1 = -36/-1
x^2 = 36
</span><span>Step 2: Take square root.
</span>x=<span>±<span>√<span>36
</span></span></span><span>x=<span><span>6 or </span>x</span></span>=<span>−<span>6

Answer:
<em>84 centimeters of the width of the item in reality</em>
Step-by-step explanation:
Let us plan out our steps, and solve for each:
<em>1. Given the information, let us create a proportionality as such:</em>
1 = 14 ⇒ x - width of item in reality (cm)
6 x
<em>2. Now let us cross multiply, and solve through simple algebra:</em>
14 * 6 = x,
<em>x = 84 centimeters of the width of the item in reality</em>
