What is the following in simplest form? sqrt(8)+3sqrt(2)+sqrt(32)

Kitty [74]

$\bf \sqrt{8}+3\sqrt{2}+\sqrt{32}\qquad 
\begin{cases}
8=2\cdot 2\cdot 2\\
\qquad 2^2\cdot 2\\
32=2\cdot 2\cdot 2\cdot 2\cdot 2\\
\qquad 2^4\cdot 2\\
\qquad (2^2)^2\cdot 2
\end{cases}
\\\\\\
\sqrt{2^2\cdot 2}+3\sqrt{2}+\sqrt{(2^2)^2\cdot 2}\implies 2\sqrt{2}+3\sqrt{2}+2^2\sqrt{2}
\\\\\\
\stackrel{like-terms}{2\sqrt{2}+3\sqrt{2}+4\sqrt{2}}\implies 9\sqrt{2}$

Which graph below shows the solutions for the linear inequality ys x-3?

liraira [26]

Answer:

Graph A.

Step-by-step explanation:

Given the inequality: $y\leq \dfrac{1}{4}x-3$

Since the sign is "less than or equal to", the line cannot be dotted. Therefore, Options C and D are incorrect.

Since the sign is a "less than" sign, the required region must be below the line. Therefore, the graph which shows the given inequality is Graph A.

A number is equal to the sum of twice the number and negative three. ... Three less than a number is translated as "x – 3." The reverse of that, "3 – x," would be a number less than 3.
