Answer:
The nth term is given by: [tex]a_n = -9 + 3(n-1)[/tex]
The 30th term is 78.
Step-by-step explanation:
Arithmetic sequence:
The nth term of an arithmetic sequence is given by:
[tex]a_n = a_1 + (n-1)d[/tex]
In which [tex]a_1[/tex] is the first term and d is the common difference between terms.
-9, -6, - 3,0
This means that [tex]a_1 = -9, r = -6 - (-9) = -6 + 9 = 3[/tex]. So
[tex]a_n = -9 + 3(n-1)[/tex]
30th term:
[tex]a_30 = -9 + 3(30-1) = -9 + 87 = 78[/tex]
The 30th term is 78.

What is 1092 using the polynomial identity (a+b)2=a2+2ab+b2 ?
Drag and drop the correct responses into the boxes.
Let the smaller value a = Response area and the larger value b = Response area. Then a2+2ab+b2 is Response area. This can be simplified to Response area. So, 1092 is equal to Response area.
Answer:
Step-by-step explanation:
The fill ups is
Smallest number, a= 9
Largest number, b= 100
a²+ 2ab+ b² can be written as 9²+ 2. 9. 100 + 100²
What is Polynomial?A polynomial is a mathematical equation that solely uses the operations addition, subtraction, multiplication, and non-negative integer exponentiation of variables. Variables are sometimes known as indeterminates in mathematics.
Given:
Here the smallest number can be taken as 9.
and, here we have 109² then the number can be split as 100 + 9.
Thus, the largest number is 100.
Now, a²+ 2ab+ b² can be written as 9²+ 2. 9. 100 + 100² which can be simplified as 11881.

11) Which answer choice is equivalent to this
n +n +n + n
C) n.
A)
4+n
(B) An
D) n(n + 3)
Answer:
4n = B
Step-by-step explanation:
N + N + N + N
Pretend that n is equaled to 2
2 + 2 + 2 + 2 is also equaled to 4 * 2 because there are four 2s.
It is just the same as n + n + n + n = 4 * n
4 * n is also written as 4n which is B.
Lets also look at the other answers.
A does not make sense because 4 + 2 (the example) does not make sense.
C does not make sense because exponents deals with multiplying n and not adding it
D does not make sense because you can already tell using the Distributive property that it is wrong
The answer is b, I hope this helps!
