We start with the given equation

x^{2} + 4 = 8

Now, we solve the equation, we subtract 4 on either side,

x^{2} +4 -4 = 8-4

x^{2}  = 4

x = \sqrt{4}

\sqrt{4 }  = +2 and -2

x = +2 or -2

So, x= +2 and x =-2

Since the given conjuncture says X=-2, we can conclude that the given conjuncture is TRUE

Twelve more than 3 times a number is more than the opposite of 11
aleksley [76]

Answer: n > \frac{-23}{3}

Step-by-step explanation:

1. So, to understand this you need to understand that the opposite of 11 is -11.

2. Use the formula 3n+12>-11.

3. Subtract 12 from both sides (3n>-23)

4. Divide by 3 on both sides. (n>\frac{-23}{3})

5. You can go a step further and simplify into -7\frac{2}{3}.

6. n > \frac{-23}{3}
