Answer:
Step-by-step explanation:
For simple integer factors as this one has, you want to find two values for the quadratic in the form ax^2+bx+c. Let the two values be j and k. These two values must satisfy two conditions.
jk=ac=10 and j+k=b=11, so j and k must be 1 and 10.
Now replace bx with jx and kx...
2x^2+x+10x+5 now factor 1st and 2nd pair of terms.
x(2x+1)+5(2x+1)
(x+5)(2x+1)
This is the concept of statistics, given that there are 650 students and all of them read a total of 18,996 pages. We are required to get the average number of pages that they all read;
Average, otherwise known as the mean is the calculated 'central' value of a set of numbers;
The formula for mean is given by;
mean=(sum)/(count)
in our case:
sum=18,996
count=650
thus;
mean=18996/650
=29.23
Here we can conclude that the average number of pages read by each student in the High School was 29.23
3x+8=5x-1
3x-5x=-1-8
-2x=-9
x=4,5
AM=3x4,5+8=21,5
MB=5x4,5-1=21,5
AB=AM+MB
AB=21,5+21,5=43
