1 figure = $17 so you multiply 4 and 17 to get 68
Martin will need to save $68
The classification would be a right triangle
If it is 1/(3x+2), 3x+2≠0 =>x≠-2/3, the domain is all real number except -2/3
if it is 1/(3x)+2, 3x≠0, x≠0, the domain is all real number except 0
It is hard to tell from your equation what the demonstrator is.
X = 12 , just solved it right now :)
