Answer:
The answer is B
Step-by-step explanation:
y=5x+2, as the slope is 5x, and the y-intercept is 2
 
        
                    
             
        
        
        
Answer:
   x^2 -x -2 = (x -2)(x +1)
Step-by-step explanation:
To factor x^2 -x -2, you look for factors of -2 that have a sum of -1:
   -2 = (-1)(2) = (1)(-2) . . . . . the latter pair has a sum of -1
Then these are the constants in the binomial factors:
   x^2 -x -2 = (x +1)(x -2)

<em>Comment on the question</em>
The fact that x^2 +3x -4 is modeled with algebra tiles seems to be irrelevant to the question that is actually asked.
 
        
             
        
        
        
The answer would be B 
Because $2.10×7 = 14.7 and $1.85×6 = 11.1 so the new were add 14.7+11.1 Hope this helps
