If two shapes are similar, they are scaled by some factor. In other words, you have
In particular, we know that
And we deduce 
So, the perimeter of ABC is
So, the perimeter of ABC is three times the perimeter of DEF, and thus it's
feets
X=2, x=-1 so the answer choice would be the third one.

Answer:
Equation: -5 + 12
Overall change: 7 yards
Step-by-step explanation:
In the problem, it says "lost 5 yards". "Lost" is another way of saying subtraction or negative. Therefore, our starting number is -5.
The problem also says "gained 12 yards". "Gained" is another was of saying addition or positive. Therefore, our second number is positive 12.
Together, these two numbers look like this: -5 + 12. To add them, go 12 to the right of -5 if on a number line. That would be like this: -5, -4, -3, -2, -1, 0, etc until you get to 7 which should be 12 more than -5.
Therefore, the answer is 7 yards.
