Answer: 6x² + 36x + 22
Step-by-step explanation:2 faces (x + 3) by (x + 7), area of both these faces 2(x+3)*(x + 7)
2 faces (x + 3) by (x - 1), area of both these faces 2(x+3)*(x - 1)
2 faces (x -1 ) by (x + 7), area of both these faces 2(x-1)*(x + 7)
Whole surface area is
2(x+3)*(x + 7) + 2(x+3)*(x - 1) + 2(x-1)*(x + 7) =
=2(x² + 3x +7x +21) + 2(x² +3x -x - 3) + 2(x² - x +7x -7)=
=2x² + 20x +42 + 2x² + 4x - 6 + 2x² + 12x -14 =
= 6x² + 36x + 22

Step-by-step explanation:
Your monthly payment would be $9.99 that is your answer to your question.
I hope this is what you are looking for have i nice week
The answer is $1.36 because you have to add $3.40+3.40 because he buys two airplanes. Afterwards you multiply times .20 and get 1.36 because you always have to move 20% two places to the left
First you had to add by six from both sides of equation form.
Then simplify.
Next you divide by three from both sides of equation form.
Finally simplify by equation.
Final answer 
Hope this helps!
