Write the conjugates of them then FOIL both the top and bottom, then factor
Answer:
1/3n=12
Step-by-step explanation:
The reason why it is 1/3n=12, is because you know that the number in front of n is 1/3. By figuring that out, you have already ruled out 3n=12 and 3n=-12. Finally, you know that 12 is a positive number leaving you with 1/3n=12.
17 x 2 = 34
54- 34 = 20
20/2 = 10 which is the width of the garden
17+5= 22
22 x 10= 220feet = the new area
