Answer:
96x^2 - 108 - 663
Step-by-step explanation:
(8x + 17)(12x - 39)
96x^2 - 312x + 204x -663
96x^2 - 108 - 663
Answer:
x=-2
Step-by-step explanation:
-9+1=-8 so 2x squared =-8
x=-2
well logically i dont think you could simplify this problem since both of your variables arent like terms... you couldnt add them because of the squared 2c. im sorry i couldnt help you
maybe check out khan academy? goodluck!
B should be the only correct answer.
You can parameterize the curve
and compute the integral along each component curve, or you can use the fact that
is the continuous gradient of a function
and observe that the line integral is path independent.
In other words, there is a function
such that
, so the integral along any curve
from the points
to
is simply
You have
, and so
while
where
is an arbitrary constant. So we've found that
which means the line integral has a value of
