Answer:
12x^2-25x-7
Step-by-step explanation:

4x*3x and 4x*-7
1*3x and 1*-7
This gives you 12x^2-4x*7+3x-7 when the like terms are combined. 
Collect the like terms, which will give you 12x^2-25x-7

Step-by-step explanation:
Excess of rent amount over annual property tax bill = annual rent - annual property tax
