The answer is 150 because you first find the area of the square which is 10x10=100 and then you find the area of the triangle which is 10x10=100 divide by 2 will give you 50 so 100+50=150 hope this helps :)
        
                    
             
        
        
        
Answer: 
Equation: 8=4b
b=2
Explanation: 
The green line equals 8 and the black time equals 2b+2b. So to form an equation where the green line equals the black line it would look like: 8=2b+2b 
8 being the green line
2b+2b being the black line 
Then the directions tell us to combine like terms, like terms are terms that are the same such as 2b in this problem, and to combine them means to add them together. 
So, 2b+2b= 4b
So the answer is, 8= 4b 
In order to solve this equation divide both sides by 4. 
Which leaves you with: 8/4= b 
Now solve 8/4:
Which gives you:
b=2
        
             
        
        
        
x^2 - 9 = (x + 3)(x -3)
3x - 9 = 3(x - 3)
and
6 
Common denominator would be 6(x+3)(x - 3)
Answer: 6(x+3)(x - 3)
 
        
             
        
        
        
Answer: an equation that represents the total costs of the gym membership based on the number of months is 
y = 25x + 50
Step-by-step explanation:
Let x represent the number of months that Frank makes use of the gym at LA fitness in order to get better in shape.
Let y represent the total cost of using the gym for x months.
He has to pay a one-time enrollment fee of $50 and then membership costs $25 per month. This means that the total cist for x month would be 
y = 25x + 50
 
        
             
        
        
        
Answer:
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
                                            10*y-(80)=0 
  Pull out like factors :
                                 10y - 80  =   10 • (y - 8)
            Solve :    10   =  0
This equation has no solution.
A a non-zero constant never equals zero.
   Solve  :    y-8 = 0  
 Add  8  to both sides of the equation :  
                      y = 8
