Which formula can be used to describe the sequence? , −4, −24, − f(x) = 6 f(x) = −6 f(x) = (6)x − 1 f(x) = (−6)x − 1

The general formula that represents the given sequence is:

Step-by-step explanation:

We are given a sequence as:

−4, −24, −144,...

The first term is:

-4.

second term is:

-24 and so on.

So, looking at the sequence the general formula that can be formed is:

Hence, the first term i..e when x=1 we have:

Similarly the second term i.e. when x=2 we have:

and so on.

Hence, the general formula is:

i do not know the answer i am sorry

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
