Answer:
24 ft²
Step-by-step explanation:
The formula to solve for area of a triangle is:
. First multiply the base x height: 12 x 4 = 48. Now multiply by 1/2: 48 x 1/2 = 24. Your answer is 24 ft².
Hope it helps and is correct!
First you solve 2y-3y=9.

Now that you have y, then you substitute y into x-2y=3 to find X

Your solution is (-15, -9)
For
to be conservative, we need to have



Integrate the first PDE with respect to
:

Differentiate with respect to
:

Now differentiate
with respect to
:

So we have

so
is indeed conservative.
1. is 9
and the other ones i dont really know
One answer is 6/10 ths; i hope this helps (;
