Factorize x^2/16+xy+4y^2

lisov135 [29]

Answer:

$\frac{x^2}{16} +xy+4y^2$ can be factored out as: $(\frac{x}{4} +2\,y)^2$

Step-by-step explanation:

Recall the formula for the perfect square of a binomial :

$(a+b)^2=a^2+2ab+b^2$

Now, let's try to identify the values of $a$ and $b$ in the given trinomial.

Notice that the first term and the last term are perfect squares:

$\frac{x^2}{16} = (\frac{x}{4} )^2\\4y^2=(2y)^2$

so, we can investigate what the middle term would be considering our $a=\frac{x}{4}$ , and $b=2y$ :

$2\,a\,b=2\,(\frac{x}{4}) \,(2\,y)=x\,y$

Therefore, the calculated middle term agrees with the given middle term, so we can conclude that this trinomial is the perfect square of the binomial:

$(\frac{x}{4} +2\,y)^2$

If you were given the data set $s $10, $10, $12, $13, $15, which measure of central

Katarina [22]

Answer: Mode

<u>Step-by-step explanation:</u>

The given data set is: 10, 10, 12, 13, 15

Mean is the average - find the sum of the data set and divide by the number of terms in the set: $\dfrac{10+10+12+13+15}{5} =\dfrac{60}{5}=12$

Mean = 12

Median is the middle term (when the data set is ordered from least to greatest).

Median = 12

Mode is the term that appears the most.

Mode = 10

Since you want to show that the prices are low, you would choose the lowest value. 10 is lower than 12, so the Mode is lower than either the Mean or the Median.
