Answer:
x = 3 and 7
There are two true solutions.
Step-by-step explanation:
To solve  , use inverse operations by squaring both sides of the equal sign.
, use inverse operations by squaring both sides of the equal sign.

The quadratic expression can be factored into binomials and set equal to 0 by the zero product property to find x.
(x - 3) ( x - 7) = 0
x-3 = 0 so x=3
x-7 = 0 so x=7
Now check each solution into the original equation to be sure it solve the solution and is not extraneous.

and 
![3-7 = \sqrt{-4(3)+28}\\[tex]-4 = \sqrt{16}\\-4 =-4](https://tex.z-dn.net/?f=3-7%20%3D%20%5Csqrt%7B-4%283%29%2B28%7D%5C%5C%5Btex%5D-4%20%3D%20%5Csqrt%7B16%7D%5C%5C-4%20%3D-4) [/tex]

Answer:
Bonnie is mixing 1.50 milliliter of soy sauce with 1 milliliter of vinegar
Step-by-step explanation:
Given
Bonnie mixes 150 milliliters of soy sauce with 100 milliliters of vinegar
So, in order to find the amount of soy sauce mixed with one ml of vinegar, we have to divide the amount of soy sauce by vinegar.
So,

Hence,
Bonnie is mixing 1.50 milliliter of soy sauce with 1 milliliter of vinegar
 
        
             
        
        
        
It would be 8 to the 8th power
        
                    
             
        
        
        
Answer:
71
Step-by-step explanation:
 
        
             
        
        
        
You can see that you're constantly subtracting 8 to get the next number. So, we have





So, as you can see, to get the n-th term we must subtract (n-1) times 8 from the original number.
