Answer:
10x^2 +2x -9
Step-by-step explanation:
Group things that are alike and simplify
(3x^2+7x^2) = 10x^2
(2x) nothing to add or subtract with it so it stays positive 2x= +2x
(-5-4) = -9
Then put the answer from highest degree to lowest
Find an explicit formula for the arithmetic sequence -45,-30,-15,0,...−45,−30,−15,0,...minus, 45, comma, minus, 30, comma, minus
juin [17]
Answer:
= 15n - 60
Step-by-step explanation:
The n th term ( explicit formula ) of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 45 and d = - 30 - (- 45) = - 30 + 45 = 15, thus
= - 45 + 15(n - 1) = - 45 + 15n - 15 = 15n - 60
