45 dogs and 52 cats because 5+7=12 so 45+7=52
(-3,2)(1,2)...notice that the y values are the same.....when the y values are the same u have a horizontal line with a 0 slope.
IF the x values would have been the same (instead of the y values), then u would have had a vertical line with an undefined slope.
Factoring the expression would be 6a(2a^2+4a-1)
So the equations are equal
