Answer:
[tex]\boxed{\bold{\left(2x-1\right)\left(4x^2+2x+1\right)}}[/tex]
Explanation:
Apply difference of cubes formula: [tex]\bold{x^3-y^3=\left(x-y\right)\left(x^2+xy+y^2\right)}[/tex]
[tex]\bold{\left(2x\right)^3-1^3=\left(2x-1\right)\left(2^2x^2+2x+1\right)}[/tex]
= [tex]\bold{\left(2x-1\right)\left(2^2x^2+2x+1\right)}[/tex]
2² = 4

Samuel is going to invest $4,900 and leave it in an account for 14 years. Assuming the
interest is compounded monthly, what interest rate, to the nearest tenth of a percent,
would be required in order for Samuel to end up with $10,300?
-
Answer:
Submit Answer
Answer:
0.053
Step-by-step explanation:
Using the compound formula A=P(1+r/n)^nt we can plug in the numbers we know. A being the total, P the initial amount, n is the number of compounds in a year, and t is the number of years passing. So 10300= 4900(1+ r/12)^12(14). We have to isolate r in order to find the rate. We can divide both sides by 4900, giving us 103/49= (1+ r/12)^168. Then we take the 168 square root from both sides. 1.00443… = 1 + r/12. Subtract 1 from both sides. 0.00443… = r/12. Then multiply both sides by twelve . r= 0.053

For just one anything that has "x" in it.
Example:
1. -9
2. +8
3. 7+x or 2x
NOTE: this varies depending on the varible after the x value. (It's not always 8)
☝Example:
5x+2 = 5x + _____
1. 3
2. +2
3. x

Answer:
7x² - 26x + 9
Step-by-step explanation:
(g(x)²) = (3x - 2) (3x - 2)
(g(x)²) = 9x² - 6x - 6x + 4
(g(x)²) = 9x² - 12x + 4
(9x² - 12x + 4) - (2x² + 14x - 5) = 7x² - 26x + 9

A cone has a volume 7065in and a height of 30 in what is the radius of the cone?use 3.14 for pi
Answer:
15 inches.
Step-by-step explanation:
V = 1/3 pi r^2 h
7065 = 1/3 * 3.14 * 30 * r^2
r^2 = 7065 / (1/3 * 3.14 * 30)
r^2 = 7065 / 31.4 = 225
r = sqrt 225 = 15.
