Answer:
60
Step-by-step explanation:
You dont have enough infor, but if its 120 degrees, A total degree of a triangle is 180, so 180-120 equals 60
6x^2+12x=0 Factor out the greatest common factor which is 6x
6x(x+2)=0
So the there are two solutions, when x=0 and x=-2
The points are, (0,0) and (-2,0)
And they expressed it as {0, -2}
Answer:
4 more than 10 is the same thing as 10 + 4
That would be 14.
