If a decimal number does not repeat, it ends with which number?
sasho [114]

Answer:

A repetend / reptend

Step-by-step explanation:

This is because most of the times this number is a 0. And a zero is normally a place holder so we don't add it. And if the repetend is zero the decimals is know as a terminating decimal.

How do you write 2x^3 + 2x^2 - 3 as a trinomial?
NARA [144]

Answer: =

6x^2−5x−6

Step-by-step explanation:  Multiply each term in one expression times each term in the other, then simplify by combining like terms.  

Here are the like terms :  =(3x+2)(2x−3)=3x(2x+3x(−3)+2(2x)+2(−3)

                                               = 6x^2−9x+4x−6

                                                     =6x2−5x−6

Which of the following is the general term for the sequence m, -m, m, -m, . . .?
bekas [8.4K]

Answer:

  A. m(-1)^(n-1)

Step-by-step explanation:

The degree of m doesn't change so none of the expressions with n as an exponent of m can possibly be correct. That leaves only choice A.

_____

You will find that when alternating signs are required, the term (-1)^n will be a factor. An offset of ±1 can be added to the n to make the initial sign be what you want. Here we want +1 for n=1, so an exponent of (n-1) is appropriate.
