Answer:
-45n-2
Step-by-step explanation:
Let's get rid of parenthesis first using distributive property!
-10n-12+10-35n
Combine like terms!
-10n-35n--12+10
-45n-2 would be the final expression
 
        
                    
             
        
        
        
y = 3(x + 4)^2 + 31
Step-by-step explanation:
We can convert the given quadratic equation into its vertex form by completing the square:
y = 3x^2 + 24x + 43
 = 3(x^2 + 8x) + 43
 = 3(x^2 + 8x + 4) + 31
 = 3(x + 4)^2 + 31
This is the vertex form of the given quadratic equation with (-4, 31) as its vertex
 
        
             
        
        
        
Answer:
25+24= 49coins 49÷2.5 is 19.5 so there are 19.5 dimes in the bag I believe 
 
        
             
        
        
        
The equation of a circle in standard form is 

where (h, k) is the center of the circle, and r is the radius if the circle.
We need to find the radius and center of the circle.
We are given a diameter, so to find the center, we need the midpoint of the diameter.
M = ((-6 + 6)/2, (6 + (-2))/2) = (0, 2)
The center is (0, 2).
To find the radius, we find the length of the given diameter and divided by 2.
