Question 1084002
-------------------------------------------------
rectangular pool is 8m longer than its width. 
------------------------------------------------


x, the width of pool
x+8, length of pool
x(x+8), just the area of the pool



---------------------------------------------------------
The pool has a walk way of 2m around the whole pool. 
---------------------------------------------------------

Combined area of pool and walkway, {{{(x+2*2)(x+8+2*2)}}}
{{{(x+4)(x+12)}}}




-----------------------------------------------
The total area of the walkway is 176m^2
-----------------------------------------------


Area of just the area of the walkway,  {{{(x+4)(x+12)-x(x+8)=176}}}

Simplify this walkway area equation.


{{{x^2+16x+48+x^2-8x-176=0}}}* MISTAKE IDENTIFIED HERE - Incorrect Sign

{{{cross(x^2+8x-128=0)}}}------------<s>Solve this for the width of pool, x, and evaluate length of pool.</s>
