Factor x3 + 2x2 + x completely.<br><br> a. (x+1)^2<br><br> b. x(x+1)^2<br><br> c. x(x+1)^2
enot [183]

Option B

<u>ANSWER:  </u>

The factors of  $x^{3}+2 x^{2}+x$ is $x(x+1)^{2}$

<u>SOLUTION: </u>

Given, cubic expression is  $x^{3}+2 x^{2}+x$

Now, we have to find the factors of above equation.

To factorize the given equation, follow the below steps:

$\mathrm{x}^{3}+2 \mathrm{x}^{2}+\mathrm{x}$

Since x is common in every term of expression, we can take it as common

$x\left(x^{2}+2 x+1\right)$

“2x” can be rewritten as “x + x”, the above equation becomes,

$x\left(x^{2}+x+x+1\right)$

Taking the common terms out of bracket. we get

x(x (x + 1) + 1 (x + 1))  

Taking (x + 1) as common., we get

x ((x + 1)(x + 1))  

$x(x+1)^{2}$

Hence, the second option b is correct.

A bird catches a fish, flies 100 yards upward in a straight line, and then drops the fish. The fish lands at a spot that is 50 y
Marina CMI [18]
You can solve this using trigonometric functions.

The angle between the fish and the ground is
tan θ = 100 / 50
θ = tan-1 (2)
θ = 63.43°

The height of the bird before it dropped the fish is already given, which is 100 yards.

Giving brainlyest to first answer<br> and id correct
Savatey [412]

Answer:

4

Step-by-step explanation:

To begin with, convert both fractions into improper fractions:

1\frac{2}{3}=\frac{5}{3} and 2\frac{3}{9}=\frac{21}{9}.

Then convert the first fraction to ninths in order to add the two:

\frac{5}{3}*\frac{3}{3}=\frac{15}{9}.

Then we add the two:

\frac{15+21}{9}

\frac{36}{9}=4

Art [367]

Answer:

The value will be used as the point estimate for the mean endowment of all private colleges in the United States is of 180.975 millions of dollars.

Step-by-step explanation:

When we have a sample, the mean of the sample is used as the point estimate for the mean of the entire population.

What value will be used as the point estimate for the mean endowment of all private colleges in the United States?

We have to find the mean of the 8 colleges. So

M = \frac{60.2 + 47.0 + 235.1 + 490.0 + 122.6 + 177.5 + 95.4 + 220.0}{8} = 180.975

The value will be used as the point estimate for the mean endowment of all private colleges in the United States is of 180.975 millions of dollars.
