Answer:
A.
Step-by-step explanation:
Take a look at what happens when squaring either of these...

Notice a couple of patterns.
1.  The last term has a positive coefficient.  That rules out answer choices C and D.
2.  The coefficient of the middle term is either  .  So what are <em>a</em>  and <em>b</em>?  <em>a</em> is the square root of the x^2 term and <em>b</em> is the square root of the y^2 term.
 .  So what are <em>a</em>  and <em>b</em>?  <em>a</em> is the square root of the x^2 term and <em>b</em> is the square root of the y^2 term.

The middle coefficient needs to be either +30 or -30.  The answer is choice A.
 
        
             
        
        
        
Answer: Greater of equal sign
Step-by-step explanation:
5+10+x is greater than or equal to 30 ( use the greater of equal to sign)
 
        
             
        
        
        
Answer:
f'(x) = b
Step-by-step explanation:
f(x) = bx 
f' (x) = d/dx (bx)
using d/dx ( a * x ) = a
f' (x) = b <-- solution.
