The answer is
3m-n
———
2n
Because the numerator can’t be simplified in a way to cancel out n or the 2.
Answer:
its C
Step-by-step explanation:
Answer:
(a) an = 18 +3(n -1)
(b) row 35
Step-by-step explanation:
(a) The general term (an) of an arithmetic sequence can be expressed in terms of the first term (a1) and the common difference (d) as ...
an = a1 +d(n -1)
The given sequence has a1 = 18 and d = 3, so the explicit formula is ...
an = 18 + 3(n -1)
__
(b) We want to find n such that an = 120.
120 = 18 + 3(n -1)
40 = 6 + n - 1 . . . . . . . divide by 3
35 = n . . . . . . . . . . . . . subtract 5
Row 35 has 120 seats.
Answer:
-2x^2-5x-15
Step-by-step explanation:
-4x^2-5(x+3)+x^2 Distribute -5 to x and 3
-4x^2-5x-15+x^2 add x^2 to -4x bc they are like terms
-2x^2-5x-15
