Step-by-step explanation:
4/5 divide
0.8 is the ans
The answer is 60.50 DO THE MATH LAZY!!!!!!!
Green's theorem says the circulation of
along the rectangle's border
is equal to the integral of the curl of
over the rectangle's interior
.
Given
, its curl is the determinant

So we have

X^2+15^2=25^2
X^2+225=625
Isolate X
X^2=400
Take the square root on both sides
X=positive and negative 20 but in this case the negative is thrown out because you can't have a negative side
Answer: 20
