Answer:

Area of gray region = $8x^2+8x-7$

Step-by-step explanation:

The area covered by the furniture can be subtracted from the total area of the room to calculate the area of the gray region.

<em>Total</em> area of the room: $13x^2+7x-2$

Area taken up by furniture: $5x^2-x+5$

Area of gray region = total area of the room - area taken up by furniture

Area of gray region = $13x^2+7x-2-(5x^2-x+5)$

Remember to distribute the negative sign:

Area of gray region = $13x^2+7x-2-5x^2+x-5$

Combine like terms:

Area of gray region = $8x^2+8x-7$
