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 = $8x^2+8x-7$

Svetach [21]

So we know that there are 12 inches in a foot. With this information we can do this: $4 \frac{9}{12}$ But if you look you can see that the fraction is not simplified. How can we simplify it? Well, what is the Greatest Common Factor of 9 and 12? Well, the answer is 3! So divide 9 and 12 by three! SO the answer would be: $4 \frac{3}{4}$ I hope this helps!
