Answer:
 (2 x +1) ( x + 1)  = 2 x² + 3 x + 1
Step-by-step explanation:
The steops used to find the product of (2 x + 1) (x + 1) are 
  =( 2 x )× x + (2 x) × 1 + x + 1
  = 2 x² + 2 x + x + 1
  = 2 x² + 3 x + 1

Answer:  
.
Step-by-step explanation:
Formula : Probability = 
From the given frequency distribution for the class level of students in an introductory statistics course, we have
Number of Junior= 12
Number of Senior = 7
Total students = 6+16+12+7 = 41
Probability that the first student obtained is a junior = 
Probability that the the second student obtained is a senior. 
Then, the probability that the first student obtained is a junior and the second a senior would be 
Hence, the required probability is 
.
