Hi Friend !!!
Here is ur answer !!!
(x-1)(x+1)(x²+1)(x^4 + 1)
= (x²-1)(x²+1)(x^4 + 1)
=( x^4 -1)(x^4 + 1)
=( x^8 -1)
The whole is with the help of (a-b) (a+b) = a²-b²

Answer:
you could use 3,5,1 as your answer, but I have a feeling you are expected to answer x = 15 / (1 - 2y) It depends on what you have been told.
Step-by-step explanation:
Take out x as a common factor.
I suspect there are many possible answers -- well more than 1 unique answer.
x (1 - 2y) = 15 Divide by 1 - 2y
x = 15 / (1 - 2y)
1 - 2y = 3
-2y = 2
y = -1
What does that give you?
1 - 2(-1) = 3
x = 15/3
x = 5
1- 2y = 5
- 2y = 4
y = -2
x = 15 / 5
x = 3
1 - 2y = 15
-2y = 15 - 1
-2y = 15
y = - 7
x = 15 / 15 = 1
-5x - 10 = 10 Thanks in advance
Answer:
x = -4
Step-by-step explanation:
10 + 10 = 20 / -5 = -4
Answer:
-5x-10=10
add 10 to both sides (why? to cancel out the -10 on the left side and make it 0 since 10+-10 = 0)
-5x=20
divide both sides by -5. to isolate x.
x=-4
Step-by-step explanation:
Solve for z
3(4z + 4) = 36
hi <3
expand the brackets
12z + 12 = 36
subtract 12 from both sides:
12z = 24
divide both sides by 12:
z = 2
hope this helps :)
Answer:
z = 2
Step-by-step explanation:
[tex]3(4z + 4) = 36[/tex]
[tex]4z + 4 = 12[/tex]
[tex]4z = 12 - 4[/tex]
[tex]4z = 8 \div 4[/tex]
[tex]\boxed{\green{z = 2}}[/tex]

There are 21 apples,28 pears and 49 oranges. These are to be arranged in heaps containing the same number of fruits. Find the greatest number of fruits possible to keep in each heap. How many heaps are formed by this arrangement?
Answer:
greatest no. of fruits possible to keep in each heap is 7
no. of heaps is 14
Step-by-step explanation:
21 apples
28 pears
49 oranges.
[tex]28 \div 21[/tex]quotient will be 1 and 7 remainder
[tex]21 \div 7[/tex]
quotient will be 3 and 0 remainder
[tex]49 \div 7[/tex]
quotient will be 7 and 0 remainder
hence, the greatest number of fruits is 7
Now,no. of heaps formed to keep fruits
Apple = 21
Pear = 28
Orange =49
Now, 21+28+49 = 98
Then, one heap can store can 7 fruits
Then,let the no. of heaps be x
x= 98÷7
x=14
Hence, no. of heaps = 14

The ratio of Mr Lim's salary to that of Mr Li is 7:8. If Mr Lim's salary is $2450, what is Mr Li's salary?
Answer:
Mr . Li's salary = $ 2950
Step-by-step explanation:
Ratio = 7 : 8
Total part = 7+8 = 15
Mr. Lim's part = 7/15
Total salary = $ x
Mr. Lim's salary = $ 2450
[tex]\dfrac{7}{15}*x= 2450\\\\\\x = 2450*\dfrac{15}{7}\\\\[/tex]
x = 370 * 15
x = $ 5550
Mr . Li's salary = [tex]\dfrac{8}{15}*5550[/tex]
= 8 * 370
= $ 2950

X/3 - X/6 = 2
What is the value of x how do I do it?
Answer:
Value of X is 18
Step-by-step explanation:
x/3 - x/6 = 2
multiply first fraction by 3 so u get X by its self then multiply the 2 by 3
x - x/6 = 6
then multiply the fraction by 6 to get X by itself then multiply the 6 by 6 because what u do to one side u have to do to the other
2x/2 = 36/2
x= 18
What is the perimeter of the triangle?
Answer:
D
Step-by-step explanation:
When you add up
[tex](4m^3+2m^2-m)+(4m^2+2m^2-2m)+(7m^3-3m^2+2m)[/tex],
you have [tex]15m^3+m^2-m[/tex],
which is what D is.
Side note:
You only add up the exponents when you multiply.
[tex]4 {m}^{3 } \: + 2 {m }^{2} \: - \: m \: [/tex]
[tex]7 {m}^{3} \: - 3 {m}^{2} + \: 2m[/tex]
[tex]4 {m}^{3} \: + 2 \: {m}^{2} \: - 2m[/tex]
Therefore ,perimeter of triangle is sum of all sides :-[tex] = (4 {m}^{3} + 2 {m}^{2} - m) + (7 {m}^{3} - 3 {m}^{2} 2m) + (4 {m}^{3} + 2 {m}^{2} - 2m)[/tex]
[tex] = 4 {m}^{3} + 7 {m}^{3} + 4 {m}^{3} + 2 {m}^{2} - 3 {m}^{2} + 2 {m}^{2} - m + 2m -2m [/tex]
