x^2 +3x-18=0\\ x^2-3x+6x-18=0\\ x(x-3)+6(x-3)=0\\ (x+6)(x-3)=0\\ x=-6 \vee x=3

Your solutions would be x = -6 or x = 3.


To find the solutions of this equation you must first factor it by finding factors of -18 that have a difference of 3. This gives you:


(x + 6)(x - 3) = 0


If you set each bracket equal to 0, you can solve for x by either adding 3 or subtracting 6 and get x equal to -6 or 3.


I hope this helps!

A bowl has 8 green grapes and 15 red grapes. Henry randomly chooses a grape, eats it, and then chooses another grape. What is th
Dmitry_Shevchenko [17]

Answer:

About 41.5%

Step-by-step explanation:

<em>Given:</em>

<em>A bowl has 8 green grapes and 15 red grapes. Henry randomly chooses a grape, eats it, and then chooses another grape. </em>

<em>To Find:</em>

<em>What is the probability that both grapes are red?</em>

<em>Answer choices:</em>

<em>about 39.7% </em>

<em>about 41.5%</em>

<em> about 42.5% </em>

<em>about 44.5%</em>

<em>Solution:</em>

<em>Since, there are 8 green grapes and 15 red grapes, the total number of grapes is 23 . </em>

<em>As the red grapes are 15.. </em>

<em>Thus, </em>

<em>The probability of choosing a red grape the first time is 15/23.</em>

<em>Because out of the total 23 grapes only 15 were red grape.</em>

<em> The probability of choosing the red grape the second time will be 14/22. Because the number of red grapes has already decreased by one and so is the total number of grapes after first choice</em>

<em>Hence, the probability of choosing or eating two red grapes will be :</em>

<em>15/23×14/22 </em>

<em>=105/253 </em>

<em>=0.415</em>

<em>= 41.5% </em>

<em>Therefore, the probability that both grapes are red is about 41.5%</em>
