factorise x ^ 4 + 1/x ^ 4 - 3
Answer:
Step-by-step explanation:
Add 1 and subtract 1, so that the expression won't change.
[tex]x^{4}+\frac{1}{x^{4}}-3=x^{4}+\frac{1}{x^{4}}-3 +1 - 1\\\\=x^{4}+\frac{1}{x^{4}} - 2 + 1\\\\= (x^{2})^{2} + (\frac{1}{x^{2}})^{2}- 2 *x^{2}*\frac{1}{x^{2}} - 1\\\\[/tex]
[tex]= (x^{2} -\frac{1}{x^{2}})^{2} - 1\\\\=(x^{2}-\frac{1}{x^{2}})^{2}- 1^{2}[/tex]
(a² - b²) = (a+b)(a - b)
Here a = x² - (1/x²) and b = 1
[tex]= [ (x^{2}-\frac{1}{x^{2}})+ 1 ] [ (x^{2} -\frac{1}{x^{2}} - 1 ][/tex]

Answer:
angle dgc=90°
angle age=30°
to find=x
angle dgc=angle agb(by vertical opposite angle)
ege is a straight line.
angle age+angle agb+angle bgf=180°[straight line measure 180°]
30°+ 90°+x=180°
120°+x=180°
x=180°-120°
x=60°

7x-4+8x=6x+8 abcdefghijklmnop
Answer:
x = 4/3
Step-by-step explanation:
7x − 4 + 8x = 6x + 8
Answer:
x=[tex]\frac{4}{3}[/tex]
Step-by-step explanation:
So the equation is 7x-4+8x=6x+8. All we need to do is simplify. On the left side, 7x+8x=15x, so 15x-4=6x+8. Now, we bring the 6x from the right side to the left. When you bring a term from one side to another, you change its sign. As of now, the sign of 6x is positive, so we make it negative and move it to the left side. The new equation is 15x-6x-4=8. Simplifying the left side gives you a new equation of 9x-4=8. Now we move the -4 from the left side to the right side. We change the sign so it becomes 4 and we move it to the right. The equation is now 9x=8+4. 8+4=12, so the final equation is 9x=12. Now we divide by 9 on both sides, giving us the unsimplified answer of x= [tex]\frac{12}{9}[/tex]. We divide the numerator and the denominator by 3 and we get our final answer of x=[tex]\frac{4}{3}[/tex].

The list shows the number of minutes that eight students spent on math homework last week. 22, 14, 24, 20, 36, 28, 43, 35What is the mean absolute deviation of the numbers
Given:
The data values are:
22, 14, 24, 20, 36, 28, 43, 35
To find:
The mean absolute deviation of the given numbers.
Solution:
We have,
22, 14, 24, 20, 36, 28, 43, 35
The measure of the given numbers is:
[tex]\overline{x}=\dfrac{\sum_{i=1}^{n} x_i}{n}[/tex]
Where, [tex]x_i[/tex] represents the observations and n is the number of observation.
So, the mean value of the given data set is:
[tex]\overline{x}=\dfrac{22+14+24+20+36+28+43+35}{8}[/tex]
[tex]\overline{x}=\dfrac{222}{8}[/tex]
[tex]\overline{x}=27.75[/tex]
The formula for is mean absolute deviation is:
[tex]M.A.D.=\dfrac{1}{n}\sum_{i=1}^{n}|x_i-\overline{x}|[/tex]
The mean absolute deviation of the given numbers is:
[tex]M.A.D.=\dfrac{1}{8}[|22-27.75|+|14-27.75|+|24-27.75|+|20-27.75|+|36-27.75|+|28-27.75|+|43-27.75|+|35-27.75|][/tex]
[tex]M.A.D.=\dfrac{1}{8}[5.75+13.75+3.75+7.75+8.25+0.25+15.25+7.25][/tex]
[tex]M.A.D.=\dfrac{1}{8}[62][/tex]
[tex]M.A.D.=7.75[/tex]
Therefore, the mean absolute deviation of the given numbers is 7.75.

A lake near The Arctic Circle is covered by a thick sheet of ice during the cold winter months. When spring arrives, the warm air gradually melts the ice, causing it’s thickness to decrease at a rate of 0.2m per week. After 7 weeks, the sheet is only 2.4m thick.
Let y represent the ice sheets thickness (in meters) after x weeks.
Complete the equation for the relationship between the thickness a number of weeks.
