If f(x)=3/x+2-root x-3 complete the following statement (round answer to the nearest hundredth) f(7)=

Hello : 
 f(x) = 3 /(x+2)  -  √(x-3)
f(7 ) = 3/(7+2) - √(7-3)
f(7) = 1/3 - √2  = 0.33 - 1.41 = - 1.1

A. p = 2(l + w)p/2 - l = ww = p/2 - l b. while isolating the variable w in the equation, i first divided both sides by 2 and then i subtracted l from both sides. i hope this .

Whose mistake? can you give more details to what the question is asking?
