Find the least common denominator for these

baherus [9]

Answer:

The least common denominator of the two rational expressions is $(x+2)^{2}\cdot (x+3)$ .

Step-by-step explanation:

Let be the following rational expressions:

$\frac{x^{3}}{x^{2}+4\cdot x + 4}, \frac{-9}{x^{2}+5\cdot x + 6}$

Then, we factor each denominator:

$\frac{x^{3}}{(x+2)^{2}}, \frac{-9}{(x+3)\cdot (x+2)}$

Now, we compare each denominator to find all missing binomials so that each expression may have a common denominator:

$\frac{x^{3}}{(x+2)^{2}} \rightarrow (x+3)$

$\frac{-9}{(x+3)\cdot (x+2)} \rightarrow (x+2)$

Hence, we conclude that least common denominator of the two rational expressions is $(x+2)^{2}\cdot (x+3)$ .

Select all solutions to the solution to the following quadratic. (x - 2)2 = 25

Makovka662 [10]

Answer:

x = 7, x = -3

Step-by-step explanation:

(x - 2)^2 = 25

Take the square root of each side

sqrt((x - 2)^2) =±sqrt( 25)

x-2 = ±5

Add 2 to each side

x-2+2 = 2±5

x = 2±5

x = 2+5, x=2-5

x = 7, x = -3

2p-b=c-ap solve for tems of p so p=bla bla bla

vitfil [10]

2p-b=c-ap

2p+ap=c+b

p(2+a)=c+b

So, p=(c+b)/(2+a)

Suppose that you have $5,000 to invest. Which investment yields the greater return over a 10 year period: 7.74% compounded daily

marin [14]

Answer:

We should invest in 7.74% compounded daily as it yields a higher return.

The total investment after 10 years is $10,841.22.

Step-by-step explanation:

a.) at 7.74% compounded daily

$final = principal(1 + \frac{i}{m} )^{m \times n} \\ = 5000(1 + \frac{0.0774}{365} )^{365 \times 10} \\ = 10 \: 841.2235$

I assumed there are 365 days in a year.

b.) at 7.8% compounded quarterly

$final = principal(1 + \frac{i}{m}) ^{m \times n} \\ = 5000 (1 + \frac{.078}{4} )^{4 \times 10} \\ = 10 \: 762.2505$
