Yes, it is reasonable. If a painter paints a fourth of a room in a fourth of a day, well that means in two-fourths of a day he would paint two-fourths of a room. Same for three fourths and four fourths, which is equal to one day. If he or she can paint one room in one day, it'd be reasonable to say that he can paint 7 rooms in 7 days.

$40+105+x=180\\
x=35$

The sum of two sides must be greater than the third side.
It can't be 5 because $5+5=10\not>12$ .
It can't be 7 because $5+7=12\not>12$ .
It can't be 17 because $5+12=17\not>17$ .
So it's 12.

Subtract.

(2x + 2) - (3x + 11)
Remove the parentheses
2x + 2 - 3x + 11
And then combine like terms
So the answer is:
-x - 9
