Answer:
= x(x+1)(x-1)
Step-by-step explanation:
Given the expression x³ - x
On factorizing
x³ - x
= x(x²-1)
Using difference of two square
a² - b² = (a+b) (a-b)
x² - 1
= x² - 1²
= (x+1)(x-1)
The complete factor
x³ - x
= x(x²-1)
= x(x+1)(x-1)

= 11.7
Write the percent as a fraction or mixed number in simplest form.
276%
Answer:when reduced to the simplest form. As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 276/100 is also equal to 2 19/25 when expressed as a mixed number.
Step-by-step explanation:
Answer: 276/100 is also equal to 2 19/25 the expressed is a mixed number.

If I is || m, find the value of y.
A. 50
B. 5
C. 27
D. 10
Answer:
D. 10
Step-by-step explanation:
8x-14=5x+34
8x-5x=34+14
3x=48
x=48/3
x=16
8x-14+5y+16 = 180
8(16)-14+5y+16 = 180
128-14+5y+16=180
5y=180-128-16+14

if Richard worked for 7 dollars and made 9 dollars and hour how much would he make?
Answer:
$63
Step-by-step explanation:
I believe you meant Richard worked for 7 hours and made $9 per hour.
In order to know how much Richard earned for 7 hours, you have to multiply Richard's salary rate with his number of working hours.
7 hours x 9 dollars/hour = $63Therefore, Richard earned $63 for his 7-hour work.
Additional Information
Another example is: if Richard worked for 10 hours, you just have to multiply his salary rate again to his number of working hours.
10 hours x 9 dollars/hour = $90Carla earn 322 points out of a 340 grade points in her environmental science course rounded up what was her percentage of points earned

Write a rule for the nth term of the arithmetic sequence described below.
A5 =
91 and a20 =
1
an=
A25=
Answer:
an = 115 + (n - 1) (-6)
a25 = - 29
Step-by-step explanation:
We use the definition for the nth term of an arithmetic sequence:
an = a1 + (n - 1) d
a5 = 91 = a1 + (5 - 1) d
91 = a1 + 4 d
a20 = 1 = a1 + (20 - 1) d = a1 + 19 d
1 = a1 + 19 d
now we subtract term by term one expression from the other
90 = 4 d - 19 d
90 = - 15 d
divide both sides by -15 to isolate d
d = 90 / (-15) = -6
Now we can calculate what a1 is using for example:
1 = a1 + 19 d
1 = a1 - 114
add 114 to both sides:
115 = a1
Then our general expression for the sequence is:
an = 115 + (n - 1) (-6)
We can now use it to calculate the value of a25:
a25 = 115 + (24) * (-6) = -29

I need some help to to solve each proportion - I want to be able to explain to my son how to do this properly. The math problem is- 4 over 6 = blank over 21 ?
Answer
The missing value is -14
Step-by-step explanation:
First you make a ratio or proportion: -4/6=x/21
Then you cross multiply
-4x21 which is -84 then 6 times x which is 6x then the equation becomes 6x=-84
from 6x you divide which becomes x=-84/6 which is -14

More info:
A proportion is simply a statement that two ratios are equal. It can be written in two ways: as two equal fractions a/b = c/d; or using a colon, a:b = c:d. The following proportion is read as "twenty is to twenty-five as four is to five."
4 x 2/4 as a mixed fraction
4 x 2/4
2/4 can be reduced to 1/2
