Combine the radicals. 2√24+5√54 A) 53√6 B) 5√6 C) 19√6 D) 93√6
love history [14]

Answer:

<h3>The answer is option C</h3>

Step-by-step explanation:

2√24 + 5√54

To combine the radicals first make sure the radicals have the same square root

That's

<h3><u>For 2√24</u></h3>

<h3>2 \sqrt{24}  = 2 \sqrt{4 \times 6}  = 2 \times 2 \sqrt{6}</h3><h3>= 4 \sqrt{6}</h3><h3 /><h3><u>For 9√54</u></h3>

<h3>5 \sqrt{54}  = 5 \sqrt{9  \times 6}  = 5 \times  \sqrt{9}  \times  \sqrt{6}</h3><h3>= 5 \times 3 \times  \sqrt{6}</h3><h3>= 15 \sqrt{6}</h3><h3 />

Since they have the same square root we can combine them

That's

<h3>4 \sqrt{6}  + 15 \sqrt{6}  = (4 + 15) \sqrt{6}</h3>

We have the final answer as

<h2>19 \sqrt{6}</h2>

Hope this helps you

Javier drove 45 miles. This represents 60% of his entire trip. What is the total number of miles in Javier's trip?
trapecia [35]
60% of trip = 45 miles

let total trip distance = <u />l

60% is given by multiplying by 0.6

So;

0.6l = 45 \\  \\  l = \frac{45}{0.6}  \\  \\ \boxed{l = 75}
