I assume
has counterclockwise orientation when viewed from above.
By Stokes' theorem,

so we first compute the curl:


Then parameterize
by

where the
-component is obtained from

with
and
.
Take the normal vector to
to be

Then the line integral is equal in value to the surface integral,



They are not equivalent fractions. You will have to turn 3/4 into an 8th, so multiply it by two, (6/8) and plot that on a graph.
Answer
8x^2+11x-9
Step-by-step explanation:
That is the answer :))
Well, 120 divided by 2 is 60
60 times 3 is 180
Betty got 180
