The slope of the line is -3/4
It’s plus 9 so the next number should be 32
There ya go, the graphing
Distribute to eliminate the parenthesis
x^2 + 2x + 6x + 12 = 60
Combine like terms
x^2 + 8x + 12 = 60
Subtract 60 from both sides
x^2 + 8x - 48 = 0
Factor the equation
(x+12)(x-4)=0
x+12=0
x+4=0
x= -12 and -4
It has a rotational symmetry of 6
So minimum number of degrees = 360 / 6
= 60 degrees
