Answer:
the distance is 10
Step-by-step explanation:
-5,2 to 0,0 is 5 
and the refection of -5,2 is 5,2
 5,2 to 0,0. is also 5
5+5=10
 
        
             
        
        
        
To solve this problem you must apply the proccedure shown below:
 1. She has a total of 50 DVDs of 90 minutes each one of them. The cost of each DVD was 11€.
 2. Therefore, to calculate the total cost of the collection, you must multiply the cost of each DVD by the total number of them:
  €
€
 3. To calculate the total minutes of the collection, you must multiply 90 minutes by the total number of DVDs:
 
 Therefore, the answer is: 550€ and 4500 minutes.
 
        
             
        
        
        
Answer:
3x^2 + 12x + 4y^2 - 8y = 32
Step-by-step explanation:
3(x^2+4x)+4(y^2-2y)=32
At first we have to break the parenthesis to get the variables in normal position. To break those, we have to multiply each with the help of algebraic expression:
or, (3*x^2) + (3 × 4x) + (4 × y^2) - (4 × 2y) = 32
or, 3x^2 + 12x + 4y^2 - 8y = 32
Since the equation does not have anything to add or deduct, therefore, it is the answer.
