Parameterize the surface (call it

) by

with

and

. Then the surface element is

The area of

is then given by the surface integral

Answer:
2/3x+2 = 4/3x-6
Solving for x:
2/3x-4/3x= -6-2
-2/3x = -8
x = -8/ (-2/3)
x = 12
Step-by-step explanation:
4+3^2•5-2

Used PEMDAS:
P Parentheses first
E Exponents (ie Powers and Square Roots, etc.)
MD Multiplication and Division (left-to-right)
