(x+1)-6(x+1)+8 how to factorise it?<br>

sergij07 [2.7K]

Answer:

Step-by-step explanation:

If you have written the question correctly, then you don't need to factor it. You only need to remove the brackets.

x + 1 + 6x + 6 + 8

7x + 15 is your final answer.

However, I think the question is

(x + 1)^2 + 6(x + 1) + 8

Let y = x + 1

y^2 + 6y + 8

(y + 2)(y + 4)

(x + 1 + 2 ) ( x + 1 + 4)

(x + 3)(x + 5)

Help me find a trend line for the data.

Hatshy [7]

A linear equation of the trend line that models the data points contained in the table is y = 0.09x + 16.27.

<h3>How to find a trend line for the data?</h3>

In order to determine a linear equation of the trend line (line of best fit) that models the data points contained in the table, we would have to use a scatter plot.

In this scenario, the body weight (in lbs) of the high school students would be plotted on the x-axis of the scatter plot while the backpack weight (in lbs) would be plotted on the y-axis of the scatter plot.

On the Excel worksheet, you should right click on any data point on the scatter plot, select format trend line, and then tick the box to display an equation for the trend line (line of best fit) on the scatter plot.

From the scatter plot (see attachment) which models the relationship between data points in the table, a linear equation of the trend line is given by:

y = 0.09x + 16.27

There are 30 students in the school chorus and 12 of these students can stay after school to help prepare the stage for the conc

Angelina_Jolie [31]

The denominator has to be the total number of kids and the numerator is the kids that can stay after school. so 12/30 then simplify. 12/30 divided by 6/6 = 2/5

5/√2+9/√8-2√50+√32 rationalise the denominator and simplify<br><br>

Alik [6]

Answer: $\displaystyle\ \Large \boldsymbol{ -\frac{5\cdot \sqrt{2} }{4}}$

Step-by-step explanation: $\displaystyle\ \Large \boldsymbol{} \frac{5}{\!\!\sqrt{2} } +\frac{9}{\!\!\sqrt{8} } -2\sqrt{50} +\sqrt{32} =\frac{1}{\!\!\sqrt{2} } \bigg(5+\frac{9}{\sqrt{4} } \bigg)+\sqrt{2} (\sqrt{16} -2\sqrt{25} ) \\\\\\\\\frac{1}{\sqrt{2} } (5+4,5)+\sqrt{2} (4-10)=\frac{9,5}{\sqrt{2} } -6\sqrt{2} =\frac{9,5-12}{\sqrt{2} } = \\\\\\-\frac{5\cdot \sqrt{2} }{4}$
