Answer:
B
Step-by-step explanation:
The differences in the terms of f(x) are + 3, + 5, + 7
Since the differences are not constant the relationship is not linear
Note the differences in the differences are + 2, + 2,
The second differences are constant indicating a quadratic relationship
Note the relationship between x and f(x)
x = 1 → 1² = 1 ← require to add 5, that is 1 + 5 = 6 ← value of f(x)
x = 2 → 2²  = 4 ← require to add 5, that is 4 + 5 = 9 ← value of f(x)
x = 3 → 3² = 9 ← require to add 5, that is 9 + 5 = 14 ← value of f(x)
x = 4 → 4² = 16 ← require to add 5, that is 16 + 5 = 21 ← value of f(x)
Thus f(x) = x² + 5 → B
 
        
             
        
        
        
Answer:
91 . 
Step-by-step explanation:
The least common multiple (LCM) of two or more non-zero whole numbers is the smallest whole number that is divisible by each of those numbers. In other words, the LCM is the smallest number that all of the numbers divide into evenly.  Glad I could help!!
 
        
             
        
        
        
Answer:
X=-0.9375 or -15/16
Step-by-step explanation:
-0.6+0.9=x+2.4
-0.6x-x=2.4-0.9
-1.6x=1.5
x= -0.9375
 
        
             
        
        
        
Answer: 21
Step-by-step explanation: In these types of problems, you use inverse operations. The inverse operation for multiplying is dividing. 42 divided by 2 is 21.
 
        
             
        
        
        
Not sure for the others but a is 55 cause ps is half a circle witch is 180 and pt is 125 so just subtract 180 - 125 =55
