In a 2 dimensional coordinate system, point A=(3, -6), point B= (1,1) and point C = (7 ,6). Find the area of triangle ABC.
The answer is 26
I thought you had to use the distance formua to find the the distance of the base and height but i'm getting some crazy radical numbers when I use the distance formula so I know there must be some other way to answer this. I hate mathhhh!! If anyone knows how to do this please help.
One more question too:
Which is the third term in the expansion of (x + 3)^5
I don't even know what the question is asking!!!
The answer is 90x^3
