Answer:
2.
3.
Step-by-step explanation:
<em>In general we can write a polynomial in standard form as </em>

<em>Given</em> 
<em>Combine the like terms: 4m and -4m</em>
<em>4m-4m=0</em>
<em>We have 4m-4m=0</em>
<em>So, write the remaining terms</em>

= 
<em>This is in decreasing order of powers.</em>
<em>Hence the answer is the standard form is</em>

<em>But in the given options, you can choose option 2 and option 3 are in standard form.</em>
<em>Because they are in decreasing order of powers.</em>
<em>In other two options, the constants term is first and the highest power term is at the last. So, they are not in standard form.</em>
<em>-2m^4-6m^2+4m+9</em>
<em>-2m^4-6m^2-4m+9</em>
<em>I hope this helps you.</em>

Answer:
45 feet 
Step-by-step explanation:
Use ratios: 

x = 540 inches 
divide by 12 to get 45 feet 
 
        
                    
             
        
        
        
Answer: 
The correct answer is d) the ratio of the change in y to the change in x along the line. 
We can tell this by looking at the slope formula. 
m (slope) = (y2 - y1)/(x2 - x1)
