This can be written as (x+4)(x+4)

Multiply everything in the second parenthesis by the x.

x^2 + 4x

Multiply everything in the second parenthesis by 4.

4x + 16

Add these two equations together.

x^2 + 4x + 4x + 16

Combine like terms.

x^2 + 8x + 16

Hope this helps!

If stratified random sampling with proportional allocation is used to select a sample of 25 high​ schools, how many would be sel
gregori [183]

Answer:

02 High Schools would be selected from the stratum with a​ percent-free-lunch value of 40 less than or equals x​.

Step-by-step explanation:

As the sample size needed is 25 and total schools are 100 so this indicate 1 school in each 4 schools is to be selected. This is given as

n=\frac{n_{total}}{n_{sample}}\\n=\frac{100}{25}\\n=4

Now as the schools with percent free lunch are 8 so now

n=\frac{n_{total}}{n_{sample}}\\n=\frac{8}{2}\\n=2

So only 2 schools will be selected in this regard.
