Answer:

x = 48°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°, thus

x = 180° - (90 + 42)° = 180° - 132° = 48°

Combine and simplify the following radical expression ASAP ASAP ASAP ASAP

Montano1993 [528]

Answer:

$\sqrt[3]{3}$

Step-by-step explanation:

Our expression is: $\frac{1}{3} \sqrt[3]{81}$ .

Let's focus on the cube root of 81 first. What's the prime factorisation of 81? It's simply: 3 * 3 * 3 * 3, or $3^3*3$ . Put this in for 81:

$\sqrt[3]{81} =\sqrt[3]{3^3*3}=\sqrt[3]{3^3} *\sqrt[3]{3}$

We know that the cube root of 3 cubed will cancel out to become 3, but the cube root of 3 cannot be further simplified, so we keep that. Our outcome is then:

$\sqrt[3]{3^3} *\sqrt[3]{3}=3\sqrt[3]{3}$

Now, let's multiply this by 1/3, as shown in the original problem:

$\frac{1}{3}* 3\sqrt[3]{3}=\sqrt[3]{3}$

Thus, the answer is $\sqrt[3]{3}$ .

Solve the compound inequality. 3x>3 or 5x<2x-3

tekilochka [14]

$5x\ \textless \ 2x-3$

$
5x-2x\ \textless \ -3
 
$ $Subtract \ 2x \ from \ both \ sides$

$3x\ \textless \ -3

 
$

$x\ \textless \ - \dfrac{3}{3}$ $Divide \ both \ sides \ by \ 3$

$x$
