which of the following is a factor in the general formula for factoring the difference of cubes?
a. (a^2-ab-b^2)
b. (a^2-ab+b^2)
c. (a^2+ab-b^2)
d. (a^2+ab+b^2)
Answer:
D: a² + ab + b²
Step-by-step explanation:
The general formula used for factoring a difference in cubes is;
a³ - b³ = (a - b)(a² + ab + b²)
Thus, the factors are either;
(a - b) or (a² + ab + b²)
Looking at the given options, the only one that is a factor is (a² + ab + b²) which is option D.
Answer:
the answer (a-b) (a^2-ab+b^2)

Will mark brainliest- please help! find x
Answer:
15
Step-by-step explanation:
Assuming x is the length DB
Δ DSR and Δ DBC are similar, so ratios of corresponding sides are equal, that is
[tex]\frac{DB}{DS}[/tex] = [tex]\frac{DC}{DR}[/tex] , substitute values
[tex]\frac{DB}{10}[/tex] = [tex]\frac{12}{8}[/tex] ( cross- multiply )
8 DB = 120 ( divide both sides by 8 )
DB = 15
That is x = DB = 15

Debra and Alexandria can finish a plowing job in two hours if they work together. Debra can do the job in 7 hours by herself. How long would it take Alexandria to finish the same job alone?
Answer:
2 hours 48 minutes
Step-by-step explanation:
Debra=1 plowing job / 7 hours
Debra+Alexandra=1 plowing job / 2 hours
1/2-1/7
=7/14-2/14
=5/14
=1/14/5 (Alexandra can do 1 unit of plowing job per 14/5 hours)
14/5 hour=2 hours 48 minutes (hope hits helps)
Alexandria to finish the same job alone in, 2 hours 48 minutes
What is mean by Subtraction?Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
Given that;
Debra and Alexandria can finish a plowing job in two hours if they work together.
And, Debra can do the job in 7 hours by herself.
Hence, We get;
For Debra = 1 plowing job / 7 hours
Debra + Alexandra = 1 plowing job / 2 hours
Hence, Time to take Alexandria to finish the same job alone is,
= 1/2 - 1/7
= 7/14 - 2/14
= 5/14
= 1/14/5 (Alexandra can do 1 unit of plowing job per 14/5 hours)
= 2 hours 48 minutes
Thus, Alexandria to finish the same job alone in, 2 hours 48 minutes

The surface area of a cube can be found using the formula S = 6e. If a cube
has an edge of 3.5, what is the surface area of the cube?
Answer:
S = 73.5 unit³
Step-by-step explanation:
[tex]A_{s} = 6e^{2}[/tex]
[tex]A_{s} = 6 (3.5)^{2}[/tex]
[tex]A_{s} = 6 (12.25)[/tex]
[tex]A_{s} = 73.5[/tex]
Answer:
73.5 unit^2.
Step-by-step explanation:
Area = e^2
Area of one face = 3.5^2 = 12.25 unit^2.
So total surface area = 6 * 12.25
= 73.5 unit^2.

What number, when added to negative five, is equal to negative four?
What number, when added to negative four, is equal to negative five?
What number, when subtracted from negative four, is equal to negative five?
Answer: What number, when added to negative four is equal to negative five.
Step-by-step explanation:
Rearange the numbers to get -4+g=-5.
This eqation now reads -4 plus a number g is equal to -5, and can also be read as what number (g) added to -4 = -5.
If we were to solve for g we would get g= -1.
Answer:
the third option, "what number, when added to negative four, is equal to negative five?"
Explanation:
"what number, when added to negative four, is equal to negative five?" can be expressed as g + (- 4) = - 5, which is the same as in the equation.

You want to determine the number of students in your school who have visited a science museum. You survey 50 students at random. Twenty have visited a science museum, and thirty have not. So, you conclude that 40% of the students in your school have visited a science museum.
A. yes; The sample is representative of the population, selected at random, and large enough to provide accurate data. So, the sample is unbiased and the conclusion is valid.
B. yes; The sample is representative of a specific group, selected based on age, and small enough to provide accurate data. So, the sample is biased and the conclusion is valid.
C. no; The sample is not representative of the population because students who are older have had more opportunities to visit a science museum. So, the sample is biased and the conclusion is not valid.
D. no; The sample is representative of the population, selected at random, and too large. So, the sample is unbiased and the conclusion is not valid
