Anumber should be rounded up if
a. it is the first digit
b. the number after it is between 0 and 4
c. the number after it is between 5 and 9
d. it is the last digit

The answer is C I just answered this question

 Option 'C' is correct.

Step-by-step explanation:

A number should be rounded up if  the number after it is between 5 and 9.

As we know the rules for "Estimation"

If there is a number after which it has between 5 and 9 , then it is rounded up to the next nearest integer.

For example :

1) 46.5

Then this number is rounded up as there is 5 in tenths place.

It becomes 47.

Hence, Option 'C' is correct.

(x3 + 6x2 + 2x - 6) • (x - 1)

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.
