You could easily do that yourself, with a pencil, and about the same amount of time it took you to post the question here.

If you go through and try them . . . 1/1,  1/2,  1/3,  1/4, 1/5 . . . etc., you'll find
that the thirds, sixths, sevenths, and ninths produce repeating decimals.
The oneths, tooths, fourths, fifths, eighths, and tenths don't.

The <em><u>correct answer</u></em> is:

3, 6, 7, 9

Explanation:

If your denominator was 1, you would have whole numbers, not repeating decimals.

If your denominator was 2, you would have halves.  These do not repeat.

If your denominator was 4, you would have 0.25 or 0.75.

If your denominator was 5, you would have 0.2, 0.4, 0.6, or 0.8.

If your denominator was 8, you would have 0.125, 0.375, 0.625, or 0.875.

If your denominator was 10, you would have 0.1, 0.3, 0.7, or 0.9.

However, if your denominator is 3, you would have repeating 3's or 6's.  If your denominator was 6, you would have a 1 with a repeating 6 or an 8 with repeating 3's.  If your denominator was 7, you would have repeating 0.142857, repeating 0.285714, repeating 0.428571, repeating 0.571428, repeating 0.714285, or repeating 0.857142.  If your denominator was 9, you would have repeating 1's, 2's, 4's, 5's, 7's, or 8's.

Factor the expression 8x^3y-8x^2y-30xy
miv72 [106K]

Find the Greatest Common Factor (GCF)

GCF = 2xy

Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)

2xy(8x^3y/2xy + -8x^2y/2xy + -30xy/2xy)

Simplify each term in parenthesis

2xy(4x^2 - 4x - 15)

Split the second term in 4x^2 - 4x - 15 into two terms

2xy(4x^2 + 6x - 10x - 15)

Factor out common terms in the first two terms, then in the last two terms;

2xy(2x(2x + 3) -5(2x + 3))

Factor out the common term 2x + 3

<u>= 2xy(2x + 3)(2x - 5)</u>

Factor x^2-10x+25,please show work
Papessa [141]
This is relatively easy because that 25 is a perfect square, whose (square) roots are 5 and -5.  x^2-10x+25 = (x - 5)(x - 5).  Note how (-5)(-5) = +25, and how -5x - 5x = -10x.

The roots are { (x-5), (x-5) }.

What is the 6th term of this sequence? 8,-12,18-27
BabaBlast [244]

Answer:

-60.75

Step-by-step explanation:

-12 / 8 = -3/2

18 / -12 = -3/2

-27 / 18 = -3/2

This is a geometric sequence with a common ratio of -3/2.

an = 8 (-3/2)^(n-1)

The sixth term is:

a₆ = 8 (-3/2)^(6-1)

a₆ = 8 (-3/2)^5

a₆ = -60.75
