It depends. You'd need to give some example, but generally the idea is to put all variables on one side and everything else on the other side.
The perimeter is 10.3. I think that's already in significant digits, but I'm not sure. We just got finished learning that in chemistry and it confused me to death!
Answer:
For as far as I know -6=a-4+b
Step-by-step explanation:
The (-4,-6) are coordinates like (X,Y) now the formula your using is y= ax+b. So the only thing you have to do is fill X and y in from the coordinates into the formula.
6yd
8yd a =48sq yd (6×8=48)
4yd
12yd a=48sq yd (4×12=48)
Rotating 180 degrees about the point p.
If they are perpendicular reflecting across each one will have the same effect as if the point was rotated 180 degrees about the certain point.
