Answer:

$23x - 10$

Step-by-step explanation:

To the find the equivalent of $9(2x - 3) + 5x + 17$ , evaluate the expression. Start by opening the bracket.

$9*2x - 9*3 + 5x + 17$

$18x - 27 + 5x + 17$

Pair like terms

$18x + 5x - 27 + 17$

$23x - 10$

The equivalent of $9(2x - 3) + 5x + 17$ is $23x - 10$

Answer:

$\sf Since \;\sqrt{\boxed{64}}=\boxed{8}\;and\;\sqrt{\boxed{81}}=\boxed{9}\; \textsf{it is known that $\sqrt{75}$ is between}\\\\\sf \boxed{8}\;and\;\boxed{9}\;.$

Step-by-step explanation:

<u>Perfect squares</u>: 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, ...

To find $\sf \sqrt{75}$ , identify the perfect squares immediately <u>before</u> and <u>after</u> 75:

64 and 81

$\begin{aligned}\sf As\;\; 64 < 75 < 81\; & \implies \sf \sqrt{64} < \sqrt{75} < \sqrt{81}\\&\implies \sf \;\;\;\;\;8 < \sqrt{75} < 9 \end{aligned}$

$\sf Since \;\sqrt{\boxed{64}}=\boxed{8}\;and\;\sqrt{\boxed{81}}=\boxed{9}\; \textsf{it is known that $\sqrt{75}$ is between}\\\\\sf \boxed{8}\;and\;\boxed{9}\;.$

See the attachment for the correct placement of $\sf \sqrt{75}$ on the number line.

Brut [27]

Answer:

(D) Pie chart

Step-by-step explanation:

The most appropriate method to represent the resulting data is the pie chart. This is because, in this sample, the variables are few and of nominal type.

Of the rest of the options, the only other that could be used is the histogram, since it can represent nominal variables with their corresponding frequency. The rest of the options have other uses not appropriate for this type of sample.
