How to do multiplying radical expressing
8_murik_8 [283]
The answer is
8 \sqrt{6}
. I've demonstrated the 'split and combine' method in the image attached.
This principal is based on the fact that you can multiply and divide radicals as you would with regular integers, but you remember that the answers remain as radicals unless the number you're dealing with is a square (e.g. 9, 16, 25).

What are the first five terms of a= 2 × n<br>​
kenny6666 [7]

Answer:

<em>2,4,6,8,10</em>

Step-by-step explanation:

To find the first 5 terms we can substitute numbers for "n"

We can create a table:

x              y

1              2

2             4

3             6

4             8

5            10

To get the values we just plug in numbers:

a(1)=2(n)

a(1)=2(1)

a(1)=2

a(2)=2(2)

a(2)=4

...... etc.

How many liters of 80% alcohol solution and 30% alcohol solution must be mixed to obtain 15 liters of 50% alcohol solution?
Margaret [11]

set up a table (multiply across and add down - <em>don't add the middle column). Use the equation created by the "Total" row to solve for the variable.</em>

               Quantity  (times)      %        equals        Total

Sol'n 1:          x            *           .80             =            (x)(.8)

<u>Sol'n 2:      15 - x        *           .30             =          (15 - x)(.3)</u>

Total:          15            *          .50              =          .8x + .3(15 - x)

                                15(.5)                        =         .8x + 4.5 - .3x

7.5 = .5x + 4.5

3.0 = .5x

6 = x

Answer: 6 liters of 80% and 9 liters of 30%
