Answer: x=3
Explain:
7x=21
21/7
Get you
3
So x equals 3
        
                    
             
        
        
        
Answer:
y = 2x^2 - 12x + 27
Step-by-step explanation:
<u>Step 1:  Distribute the power</u>
y = 2(x - 3)² + 9
y = 2(x^2 - 6x + 9) + 9
y = 2x^2 - 12x + 18 + 9
y = 2x^2 - 12x + 27
Answer:  y = 2x^2 - 12x + 27
 
        
             
        
        
        
1/3=2/6
5/6x2/6= 10/36
10/36 simplified is 5/18 
        
             
        
        
        
Answer:
B
Step-by-step explanation:
To find the area, multiply length by width (lw, or l×w). If the length is 10, that just leaves the width, which is unknown. We can substitute 10 for l, which leaves us with 10w.
 
        
             
        
        
        
Answer:
