11.16 repeat only the six is repeating
        
                    
             
        
        
        
29% = 0.29
Multiply 1.89 with 0.29
1.89 x 0.29 = 0.5481
Note that it is a markdown, so subtract 0.55 (rounded) with 1.89
1.89 - 0.55 = 1.34
The spark plug now costs ~ $1.34
hope this helps

Answer:
Step-by-step explanation:
(x+3)² -5 =0 , use the formula (a+b) ² = a²+b²+2ab
x²+9 +6x -5 =0 , combine like terms
x²+6x +4 =0, use the quadratic formula x = (-b±√b²-4ac)/2a
x= (-6 ±√6²-4*1*4)/2*1 
x= (-6 ± √36-16) /2
x= (-6±√20)/2 
x=(-6 +2√5)/2 and x=( -6-2√5) /2, factor 2 in the numerator and simplify 
x= -3 +√5 and x= -3 -√5
 
        
             
        
        
        
Answer:
a)

B) 
He ordered 12 books
Step-by-step explanation:
so each book (b) costs $6. he payed $75 total including the $3 shipping price
That gets us:
6b+3=75
6b=72
b=12
Therefore, Tom ordered 12 books
