Answer: 6x^(2)+4x^(2)y or 4x^2y+6x^2
ANSWER
2(s+175)
EXPLANATION
The total amount of garbage thrown away at the school each day is the amount of garbage thrown away by the students plus the amount of garbage thrown away by non-students.
total = lb students + lb non-students
lb students is 2s as each student throws away two pounds a day.
lb non-students is 350. Therefore, the total amount of pounds of garbage thrown away each day is
total = 2s + 350
We can factor out a 2 from this expression as each term is divisible by 2 and that is the greatest common factor. We end up with
total = 2(s+175)
First we will find the 11th term
an = a1 + (n-1) * d
a11 = 12 + (11 - 1) * 5
a11 = 12 + 10 * 5
a11 = 12 + 50
a11 = 62
now we use the sum formula...
Sn = (n (a1 + an)) / 2
S11 = (11 (12 + 62)) / 2
S11 = (11 (74)) / 2
S11 = 814/2
S11 = 407
3/4 is the answer for your question
I think - 14 or 14 but I am not sure.
