The equation 13x+30=134 can be used to find the number of months Kenneth can receive internet service.

Step-by-step explanation:

Given,

Start up fee to receive internet = $30

Per month charges = $13

Total amount = $134

Let,

x be the number of months.

y be the total cost.

y = 13x+30

Putting y=134

134=13x+30\\13x+30=134

The equation 13x+30=134 can be used to find the number of months Kenneth can receive internet service.

Simplify.<br> √20⋅√3·√18<br><br> 5√30<br><br> 5√10<br><br> 6√10<br><br> 6√30
ddd [48]

The correct answer is:   [D]:  " 6√30 " .


_____________________________________


Explanation:


_____________________________________


Simplify:   " √20 ⋅ √3 · √18 " :


___________________________


Step 1)  Simplify the "first term" :

"√20  " = √4 √5 = 2√5  ;


___________________________


Step 2):  Consider the "second term:  

                  "√3 " = √3  (already simplified); 


___________________________


Step 3)  Simplifly the "third term" :

" √18  "  =  √9 * √2 =  " 3√2 " ;


____________________________

We have:  " 2√5 * √3 * 3√2 " ;

                 =   (2* 3) *  (√5 * √3 * √2) ;

                 =  6 * (√5 √3 √2)  ;

Note:  " (√5 * √3 * √2 )"  =   " √(5 * 3 * 2) "  =  " √ 30 " .

So:    " 6 * (√5 * √3 * √2)  =

______________________________________

          →   " 6 √30 " .

______________________________________

The answer is:  " 6√30 " ;

       →  which is:  "Answer choice:  [D]:  " 6√30 " .

_____________________________________

Hope this answer helps!

Best wishes!
