3. (x2 + 17x + 63) ÷ (x + 8) =

Stolb23 [73]

$3(2x + 17x + 63) \div (8 + x) \\ 6x + 51 + 189 \div 8x$
$6x \times 8x = 48x$
$51 + 189 \div 48x \\ 240 \div 48x \\ 5x$
= 5x

Use the Quotient Property to Simplify Square Roots Number 129

Inessa05 [86]

Using the quotient property we would have

$\begin{gathered} \sqrt{\frac{75r^9}{8^8}}=\frac{\sqrt{75r^9}}{\sqrt{8^8}} \\ \end{gathered}$

This follows the rule

$\sqrt{\frac{a}{b}}=\frac{\sqrt{a}}{\sqrt{b}}$

From the simplified expression as shown above

$\frac{\sqrt{75r^9}}{\sqrt{8^8}}=\frac{\sqrt{3\times25\times r^9}}{\sqrt{(2^3)^8}}$

Thus;

$\frac{\sqrt{3\times25r^9}}{\sqrt{(2^3)^8}}=\frac{\sqrt{25}\times\sqrt{3}\times\sqrt{r^9}}{\sqrt{2^{^3\times8}}}=\frac{5\sqrt{3r^9}}{\sqrt{2^{24}}}$

Therefore

$\begin{gathered} Using\text{ fraction index law we could simplify the denominator} \\ \frac{5\sqrt{3r^9}}{2^{\frac{24}{2}}}=\frac{5\sqrt{3r^9}}{2^{12}} \end{gathered}$

We can not simplify the 3 and the r raised to power of 9 as their power is not even, hence the final answer is given below

$\frac{5\sqrt{3r^9}}{2^{12}}=\frac{5\sqrt{3r^9}}{4096}$

The final answer is :

$\frac{5\sqrt{3r^9}}{4096}$

Here are the fuel efficiencies (in mpg) of 10 new cars.

Alenkasestr [34]

Answer:

20%

Step-by-step explanation:

Cars that are less than 19 mpg : 16, 18

2 cars have less than 19 mpg.

2/10 cars have less than 19 mpg.

To change fraction to percentage :

divide the numerator by the denominator, then multiply the decimal by 100

2/10 = 0.2

0.2*100 = 20

20%
