First we will find the area of the wall
The height of the wall = 9 ft
Width of the wall = 10 ft
So area of wall = height*width
area= square feet
And the rest painted area was = 46 square feet

So, a gallon of paint covered 136 square feet area.
Answer: a^2x^2+9x^2+13x+6a
Step-by-step explanation:
(a^2+9) x^2+ 13x +6a
x^2(a^2+9)+13x+6a
Expand:x^2(a^2+9): a^2 x^2+9^2
x^2 a^2 +x^2*9
a^2 x^2+9x^2
a^2 x^2+9x^2+13x+6a
