The function is f(x)=2x+10
The answer: x is equal to 50
First, multiply 6 in by 3 to get 18 ft as the length of the living room.
6•3=18
Next, multiply 5 in by 3 to get 15 ft as the width of the living room.
5•3=15
Then multiply 18 by 2 and 15 by 2 and add the products together.
(18•2)+(15•2)=66
This makes the answer 66 ft.
