Answer:
C. $16.00
Step-by-step explanation:
First, let's find how much they profit from one loaf 
The profit is the difference between how much they sell it for and what they buy it for. 
So, we can subtract what they buy the bread for from how much the sell it for 
selling price-buying price 
2.40-0.80=1.6 
So, they profit $1.60 per loaf 
To find how much they profit for 10 loaves, multiply their profit from one loaf by 10 
profit*10 
1.60*10=16 
The profit for 10 loaves is $16, or choice C
 
        
             
        
        
        
Answer:
1+cos^2(2A)=(1−cos2(2A))+2cos^2(2A)
=sin^2(2A)+2(cos^2A−sin^2A)^2
=(2sinAcosA)^2+2(cos^4A−2cos^2Asin^2A+sin^4A)
=2(cos^4A+sin^4A)

Answer:
-(2y+3)×(3y+5)
Step-by-step explanation:
- 3y(2y + 3) - 5(2y + 3)
Factor out - (2y+3) 
-(2y+3)×(3y+5)
 
        
             
        
        
        
Answer: No solution
Step-by-step explanation:
Let one number be x
Other no. will be 2x
x - 1/2(2x) = 20
x - x = 20
No solution
