Answer:
(x² - 3)(x² + 3)([tex]x^{4}[/tex] + 9)
Step-by-step explanation:
[tex]x^{8}[/tex] - 81 ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b)
[tex]x^{8}[/tex] - 81
= ([tex]x^{4}[/tex] )² - 9²
= ([tex]x^{4}[/tex] - 9)([tex]x^{4}[/tex] + 9) ← [tex]x^{4}[/tex] - 9 is also a difference of squares
= (x² - 3)(x² + 3)([tex]x^{4}[/tex] + 9)
Answer:B

Steve said that [5, 12) is the interval notation that represents the set of all real numbers greater than or equal to 5 and less than 12. Joe says that (5, 12] is correct interval notation. Who is correct and justify why?
Answer:
Steve was correct in his statement.
Step-by-step explanation:
According to standard notation, opening bracket ( [tex][[/tex] ) represents the lower bound of a set so that elements of the set are equal or greater than lower bound.

Sally, Emma and James have a total of 52 nerf toys. If James had 6 more, then he would have as many as both girls combined. Emma has three more toys than Sally. How many nerf toys do each of the three have.
(Please answer quickly it's due tomorrow morning)
Answer:
emma: 6 toys, sally: 13 toys, james: 23 toys
Step-by-step explanation:
if emma had x toys, sally would have (x-3) toys. and we know that if james had 6 more toys, he would have the same amount as both girls combined. so in this case in terms of x, james would have (x+x-3-6) toys, after simplification we get 2x-9 toys..
since we know that the three of them have 52 nerf toys as total, we can set up the equation:
x= number of toys emma has
2x-9+x+x-3=52
4x-12=52
x=16
emma has 16 toys, and sally has (16-3)=13 toys. finally, james has (2*16-9)=23 toys. 16+13+23=52

15% of y is 30 what equation could be used to solve
Answer:
Y= 200
Step-by-step explanation:
Just divide 30 by 0.15
Hope that helps!
Answer: y = 30/0.15
Step-by-step explanation:
First, convert 15% to a decimal by dividing by 100 to get 0.15. The word "of" in an equation means multiply, so the equation would be y*0.15 = 30. To isolate the variable you're trying to solve for, divide both sides by 0.15. The 0.15 on the left side of the equation cancels out, leaving you with a final equation of y = 30/0.15.

Fill in the following table so that the sum of the numbers in first three cells is equal to 300, the sum of the three numbers in the middle is 200, and the sum of the last three is 100. What is the number that stands in the middle?
Answer:
The number in the middle is 60.
Step-by-step explanation:
The 2nd number = A
The 3rd number = B
The 4th number = C
Given:
(1) 130 + A + B = 300
(2) A + B + C = 200
(3) B + C + 10 = 100
Now, the work:
(2) can be modified to become A + B = 200 - C
Now, we can insert that into (1) and get the following;
130 + (200 - C) = 300
Open parentheses, simplify, you get C = 330 - 300.
C = 30
Using (3), we use above answer to get B + 30 + 10 = 100
Calculate, and get B = 100 - (30 + 10)
Simplify,
B = 60
There is your answer!

(100 points;)The area of a right triangle is 39.6 in², and the base of the triangle is 12 inches.
Which of the following values is the height of the triangle?
303 in.
1.65 in.
6.6 in.
6.1 in.
The answer is 6.6 inches
AREA OF TRIANGLE = 1/2 X BASE X HEIGHT
=> 39.6=12XH/2
=> 39.6X2=12XH
=> 79.2 = 12XH
=> 79.2/12= H
=> 6.6
Solution:
Given:
Area of right triangle = 39.6 in²Base of triangle = 12 inArea of triangle formula: 1/2 x Base x Altitude
Substitute the area and the base:
1/2 x Base x Altitude = Area of right triangle1/2 x 12 x Altitude = 39.6 in²Simplify the LHS:
1/2 x 12 x Altitude = 39.6 in² 6 x Altitude = 39.6 in²Divide 6 both sides:
(6 x Altitude)/6 = 39.6/6Altitude = 6.6 in.Pip was thinking of a number. Pip doubles it and gets the answer of 50.8. What was the original number?
Answer:
25.4
Step-by-step explanation:
If double of the number 'x' is 50.8, (2x=50.8)
Then the original number must be half of that value, (x=50.8/2)
50.8/2 = 25.4
