Factors of the given expression are (x+4), (2x+1)

Given expression is

2x^2 + 9x+4

<h3>What is a factor?</h3>

A factor is a number that divides another number completely.

Let us split the middle term as:

2x^2 + 8x + x+4\\\\2x(x+4)+1(x+4)\\\\(x+4) (2x+1)

Therefore, factors of the given expression are (x+4), (2x+1)

Which term does not belong with the other three
AnnyKZ [126]

It seems that you have missed few parts of the question.

I searched that question on internet and got the complete question as follows:

Which term does not belong with the other three: lines, segments, planes, and rays?

Answer:

Line, segments and rays all are 1-dimensional quantity like they move in just one direction. While plane is a 2-dimensional quantity like it has length and breadth.

In that case term "plane" doesn't belong with the other three.


Hence final answer is "plane".

Pavlova-9 [17]

Answer:

follows are the solution to this question:

Step-by-step explanation:

Please find the correct question in the attached file:

The formula for calculating the Confidence interval of proportion:

\to CI=\hat{p} \pm Z_{\frac{\alpha}{2}} \sqrt{\frac{\hat{p}(1-\hat{p})}{n}}\\\\\to  \hat{p}=\frac{\text{lower limit +upper limit}}{2}\\

      =\frac{0.48+0.60}{2}\\\\=\frac{1.08}{2}\\\\=0.54

The number of learners with access to working at home on a computer:

= 0.54 \times 300 \\\\=162

Lower limit =0.48

upper limit = 0.60

\to margin \ error = \frac{\text{upper limit - lower limit}}{2}\\

                          =\frac{0.60-0.48}{2}\\\\=\frac{0.12}{2}\\\\= 0.06
