Which expression is equivalent to 7h^2-252k^2?

gulaghasi [49]

Answer:

Step-by-step explanation:

252 = 7 *36

36 = 6 *6 = 6²

a² -b² = (a + b)(a - b)

7h² - 252k² = 7(h² - 36k²)

= 7(h² - [6k]² )

= 7(h +6k)(h - 6k)

A company conducted a survey to see whether its new toothpaste was morepopular with children or adults. Of the children surveyed

Naily [24]

Given: The information provided in the table shown

To Determine: From the options provided, the correct option that best describe the information given in the table

Solution

Given that 28% of the children used toothpaste. From the table

$Children(toothpaste)=\frac{0.07}{0.25}=\frac{7}{25}\times100=28\%$

Let us calculate the percentage of adult that used toothpaste

$Adult(toothpaste)=\frac{0.08}{0.75}=\frac{8}{75}\times100=10.667\%\approx11\%$

Hence, a smaller percentage of adults (about 11%) use the toothpaste.

The correct option is OPTION C
