Explain how combining like radicals is similar to combining like terms.

pickupchik [31]

Answer:

Just like combining like terms with the same variables, you combine like

radicals with the same number under the radical signs.

Step-by-step explanation:

Example:

3x + 2x

= 5x {combined like terms}

3√2 + 2√2

= 5√2 {combined like radicals}

You have 1 case of soap bars and there are 150 bars in a case. You use 300 bars of soap per day. How many cases do you need to o

diamong [38]

Answer:
14 cases

Explanation:
First, we will need to find the number of cases needed per day:
We know that one case includes 150 bars and that the daily consumption is 300 bars. To know the number of cases needed daily, we will use cross multiplication as follows:
1 case .............> 150 bars
?? cases .........> 300 bars
number of cases needed daily = $\frac{300*1}{150}$ 
number of cases needed daily = 2 cases

Then, we will get the number of cases needed weekly (7 days):
We know that 2 cases are needed daily. To know the number of cases needed weekly (7 days), we will simply use cross multiplication as follows:
1 day .............> 2 cases
7 days ...........> ?? cases
number of cases needed weekly = $\frac{7*2}{1}$ 
number of cases needed weekly = 14 cases

Hope this helps :)

Explain how to use a pattern to find 35.6 divided by 10 to the power of 2

posledela

As we know, sometimes questions such as these that include the powers and patterns can be a little confusing. I'll walk you through the process of finding this answer.

Firstly, we both know that 10 to the power of 2 simply means this :

10 * 10 = 100

Now, considering we already know what 10 to the power of 2 is, it makes the rest of the question a lot easier. All we have to do is divide 35.6 by the numbers we got.

35.6 / (10 * 10) = 0.356

There you have it, the answer is 0.356. If you need further assistance or you don't understand something, don't hesitate to ask me! I'm always open to people commenting on my profile or even sending me a private message. :)
