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

Diana has 1 square yard of fabric she will make one pillow that requires 3/8 square yard of fabric and another pillow that requi
Scilla [17]

Answer:

<h2>Diana uses 5/8 square yard of fabric for both pillows.</h2><h2>There remains 3/8 square yard of fabric.</h2>

Step-by-step explanation:

Givens

  • The total amount of fabric is 1 square yard.
  • One pillow requires 3/8 square yard of fabric.
  • A second pillow requires 2/8 square yard of fabric.

To find the total amount of fabric Diana used, we must sum those fractions

\frac{3}{8} +\frac{2}{8}=\frac{5}{8}

Diana uses 5/8 square yard of fabric for both pillows.

Now, we subtract to find the remaining amount of fabric

1-\frac{5}{8}=\frac{8-5}{8}=\frac{3}{8}

Therefore, there remains 3/8 square yard of fabric.
