Solve the problem.The area of a square is numerically 21 more than the perimeter. Find the length of the side.
A. 7 units B. 28 units C. 25 units D. 98 units
z = f (x, y) = y ?x; a = 25, b = 5, x = 7.28, y = 8.51
For the following functions, use linearization and the values of z, 
at (a b) to estimate z (x, y) .
Decide if the given value of x is a critical number for f, and if so, decide whether the point is a relative minimum, relative maximum, or neither.f(x) = x11/5 + x6/5; x = 
A. Not a critical number
B. Critical number, relative minimum at 
C. Critical number but not an extreme point
D. Critical number, relative maximum at
