Answer:

Step-by-step explanation:

1) a² - b² = (a + b)(a- b)

2) a³ + b³ = a³ + 3a²b + 3ab² + b³

3) a³ - b³ = a³ - 3a²b + 3ab² - b³

5) x⁴ - 36 = (x²)² - 6² = (x² + 6) (x² - 6)

6)64c³ +  1 = (4c)³ + 1³ = (4c)³ + 3(4c)²(1) + 3(4c)(1)³ + 1³

                  = 64c³ + 3(16c²) + 12c +1  

                   = 64c³ + 48c² +12c + 1

7) k³ - 27 = k³- 3³ =  (k + 3)(k - 3)

Answer:

Step-by-step explanation:

the formula for the differences of squares  a^2-b^2  = (a+b) (a-b)

The formula for Sum of Cubes a^3-b^3= (a-b)(a^2+ab+b^2)

The formula for Difference of Cubes a^3-b^3= (a-b)( a^2+ab+b^2)

You can put this as answers for 1-3

4.Multiply the answer to see if you get the original polynomial.

and also use this formula to solve question 5-12

for x^4-36 you can use differences of squares formula  a^2-b^2  = (a+b) (a-b)

we need to rewrite x^4-36 as (x^2)2 -6^2

a=x^2 and b=6

So

(x^2+6)(x^2-6)

follow same step for rest let me know if you need more help

Step-by-step explanation:

Obliged to you for hearing me, and now old Sojourner ain’t got nothing more to say.

This Implies that she needs to say nothing more, because the truth was so blaringly obvious that everyone in the crowd understood it. It also implies that no better argument for her cause could be put forward, and none was needed.

In 1985, there were 285 cell phone subscribers in Arlington. The number of subscribers increased by 75% per year since 1985. Fin
ANTONII [103]

Answer:

The number of subscribers in 2008 is 110,845,988

Step-by-step explanation:

The number of cell phone subscribers in Arlington, in t years after 1985, can be modeled by the following equation.

N(t) = N(0)(1+r)^{t}

And which N(0) is the number of subscribers in 1985 and r is the rate it increases per year, as a decimal.

In 1985, there were 285 cell phone subscribers in Arlington.

This means that N(0) = 285

The number of subscribers increased by 75% per year since 1985.

This means that r = 0.75

So

N(t) = 285(1.75)^{t}

Find the number of subscribers in 2008.

2008 is 2008-1985 = 23 years after 1985. So we have to find N(23).

N(23) = 285(1.75)^{23} = 110,845,988

The number of subscribers in 2008 is 110,845,988
