You would use PEMDAS
P stands for parentheses, x-5 can’t be simplified, so on to E.
E stands for exponent so next you would square x-5 getting x^2-10x+25.
M stands for multiplication, you multiply your result from E by -2. So, -2(x^2-10x+25)+8. And then -2x^2+20x-50+8.
D stands for division, and there is none so moving on.
A stands for addition, and so we add next. -2x^2+20x-42.
You can’t simplify any further so there you go!
Hope this helps!
                                
             
                    
              
              
                
                
Hey there! 
Just distribute: 
2(x - 5)^2 + 8
= 2x^2 + 20x - 50 + 8
Combine your like terms 
-50 & 8
= -50 + 8 ➡️ -42
Answer: 2x^2 + 20x + -42

3/4 tons = 1500 lbs/pounds
        
                    
             
        
        
        
There are 64 ounces total in a half gallon
        
                    
             
        
        
        
Divide 20 by 10 you get 2 wholes with no remainder so your answer is 2
