Answer:

The LCM of 9, 12, and 24, is <em>72.  </em>

Step-by-step explanation:

To find the answer you must figure out the factors of <em>each number</em>, and see which factor has the <em>same number.</em>  

<u><em>Factors of 9: </em></u>         <u><em>Factors of 12:</em></u><em>        </em><u><em>Factors of 24: </em></u>

     <em>  9                            12                          24</em>

<em>        18                          24                          48</em>

<em>        27                          36                         72</em>

<em>        36                          48</em>

<em>        45                          60</em>

<em>        54                          72</em>

<em>        63</em>

<em>        72</em>

When we look at all these factors, none of them have the same number <em>except 72.</em>  Since <em>all</em> of these factors have <em>72 in them</em>, this is the<em> </em>LCM of 9, 12, and 24.

3(-10n + 9) - 3(1 + 8n)= 24
Arlecino [84]

Answer:

n=0

Step-by-step explanation:

Let's solve your equation step-by-step.

3(−10n+9)−3(1+8n)=24

Step 1: Simplify both sides of the equation.

3(−10n+9)−3(1+8n)=24

(3)(−10n)+(3)(9)+(−3)(1)+(−3)(8n)=24(Distribute)

−30n+27+−3+−24n=24

(−30n+−24n)+(27+−3)=24(Combine Like Terms)

−54n+24=24

−54n+24=24

Step 2: Subtract 24 from both sides.

−54n+24−24=24−24

−54n=0

Step 3: Divide both sides by -54.

−54n/-54=0/−54

n=0

Answer:

n=0

Im in algebra II honors and right now we are working on parabolas and quadratic equations. Can someone help me understand how to
Maurinko [17]

f (x) = a(x - h)2 + k, where (h, k) is the vertex of the parabola. FYI: Different textbooks have different interpretations of the reference "standard form" of a quadratic function.

The standard form of a parabola is y=ax2++bx+c , where a≠0 . The vertex is the minimum or maximum point of a parabola. If a>0 , the vertex is the minimum point and the parabola opens upward. If a<0 , the vertex is the maximum point and the parabola opens downward.
