(type an integer or a simplified fraction. use a comma to separate answers as needed.)
b . the solution is not a real number
o
solve for x

The value of x is 5 , - 5

Step-by-step explanation:

Given as :

(x + 3) + (x - 3) = 4

Now, from log property

(x + 3) + (x - 3) =

So,  (x + 3) × (x - 3) =

Or,  x² - 9 = 16

or,  x² = 25

∴  x =

I.e x = 5

Hence the value of x is 5 , - 5  Answer

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.
