A Harvard Graduate says 11 + 1 = 13. Is he correct? 100% true. or 0% true.

0% true

Step-by-step explanation:

because 11+1= 12 not 13

and 100% true means that it is true when it isn't. And 0% true means its not true which is the answer.

Hope this helps. :)

answer: a parabola

steps:

(x-1)(x+4)   = x(x+4) - 1(x+4) = (x^2 + 4x) - (x+4)

                = x^2 +4x -x -4   = x^2 +3x -4

which is a parabola
