Answer:

5x2 - x + 6

Step-by-step explanation:

(6x2-x+8)-(x2+2)

We gonna use KCC which is Keep Change Change and distributing property

multiple (6x2-x+8) by 1 and (x2+2) by -1

6x2-x+8 -x2 - 2

combine the like terms

6x2 - x2 + 8 - 2 - x

5x2 + 6 - x

arrange in order

5x2 - x + 6

Answer:

c) (40+60+25)/200 or 63%

Step-by-step explanation:

n= 200 students

Did Well on the Midterm and Studied for the Midterm = 75

Did Well on the Midterm and Went Partying = 40

Did Poorly on the Midterm and Studied for the Midterm = 25

Did Poorly on the Midterm and Went Partying = 60

The number of students that did poorly on the midterm or went partying the weekend before the midterm is given by the sum of all students who did poorly to all students who went partying minus the number of students who did Poorly on the Midterm and Went Partying:

$N=(25+60)+(40+60) - 60\\N= 125$
