Answer:

Five groups of five tenths and nine hundredths

Step-by-step explanation:

Mathematically;

2.36 divided by 4 = 0.59

So we want to select from the options, the best representation of this

That will be

0.5 + 0.09

so our answer is 5 groups of five tents and nine hundredths

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.

Write a linear function f with the given values. f(0) = -2,f(4) = -3
Thepotemich [5.8K]

Answer:

<em>f(x) = </em>-\frac{1}{4}<em> x - 2 </em>

Step-by-step explanation:

Slope of the line: m = \frac{y_{2} -y_{1} }{x_{2} -x_{1} }

y - y_{1} = m( x - x_{1} )

f(x) = mx + b (b - is y-intercept)

(0, - 2) Coordinates of y-intercept

(4, - 3)

m = \frac{-3+2}{4-0} = -\frac{1}{4}

<em>f(x) = </em>-\frac{1}{4}<em> x - 2</em>
