-3 (x - 5) - 8 (y + 2) + (-3) (6 - 4b)
First, simplify your brackets. / Your problem should look like: -3 (x - 5) - 8 (y + 2) + -3 (6 - 4b)
Second, simplify. / Your problem should look like: -3 (x - 5) - 8 (y + 2) - 3 (b - 4b)
Third, expand your problem. / Your problem should look like: -3x + 15 - 8y - 16 - 18 + 12b
Fourth, simplify. / Your problem should look like: -3x - 8y + 12b - 19
Answer: -3x - 8y + 12b - 19 (D)
        
                    
             
        
        
        
Answer:
$9 per flower
Step-by-step explanation:
divide cost ($90) by the number of items (10 flowers)
 
        
                    
             
        
        
        
Ten thousands place because the dight before the is thousands and the dight after the four is the hundred thousands
        
             
        
        
        
 You can factor a parabola by finding its roots: if

has roots  , then you have the following factorization:
, then you have the following factorization:

In order to find the roots, you can use the usual formula

In the first example, this formula leads to

So, you can factor

The same goes for the second parabola.
As for the third exercise, simply plug the values asking

you get

Add 3 to both sides:

Divide both sides by 1.5:
