Answer: 49
Step-by-step explanation:
Answer:
x=±√−9
No real solutions.
Step-by-step explanation:
Step 1: Add 3x^2 to both sides.
27+3x2=−3x2+3x2
3x2+27=0
Step 2: Subtract 27 from both sides.
3x2+27−27=0−27
3x2=−27
Step 3: Divide both sides by 3.
3x2
/3
=
−27
/3
x2=−9
Step 4: Take square root.
x=±√−9
For a vector-valued function
the matrix of partial derivatives (a.k.a. the Jacobian) is the 
matrix in which the 
-th entry is the derivative of 
with respect to 
:
So we have
(a)
(b)
(c)
(d)
alr! so we know that the top line is straight, so it=180 degrees. then we know...
2x + 20 + 2x - 4= 180
4x + 16=180
4x=164
x=82
youre welcome!
