Answer:
91
Step-by-step explanation:
Todd’s average score for six tests = 92.
The sum of two of her test = 188
First, we need to find the total score for the six test. This given below:
Average = sum of all test / number of test
sum of all the test = average x number of test 
average score for six tests = 92.
Number of test = 6
Sum of all the Tests = 92 x 6 = 552
Sum of four test = sum of all the test — sum of two test 
Sum of four test = 552 — 188 = 364
Now we can solve for the average of the other four test as shown below:
Average of four test = 364/4= 91
 
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
The Fundamental Theorem of Algebra states that the number of complex roots a polyomial has is equal to its highest exponent.  This is a squared polynomial; second degree; quadratic.  When it is factored, no matter what types of numbers you get as the solution, you will ALWAYS have 2 of them.  When this quadratic is factored, we get that x = 3 and x = 3.  That means that this is a quadratic that touches the x-axis at (3, 0).  It doesn't go through, it only touches.  We do have 2 roots, but since they're the same, we say we have a multiplicity 2 of that root.  The closest you'll come to that in your choices is A.  Apparently your text refers to multiplicity 2 as a double root.
