30% of all the students in a school are in a play all students except for 140 are in the play how many students are in the schoo
Bezzdna [24]
To figure out how many kids are in the school, you must set up an equation with x representing the number of students. 30% of the students are in the play, so that would be represented by 0.3x. We also know that 140 students are not in the play, that could be represented by x-140. These two equations will equal each other since they both represent the same information, which is the number of children in the play. You set those two equations equal to one another (0.3x = x-140). You then can add 140 to the left side of the equation and subtract 0.3x from the right side. We do this in order to get both values of x on the same side of the equation. We then can simplify the right side of the equation by subtracting 0.3x from 1x. We get 0.7x. Our equation now looks like 140 = 0.7x. We must now divide each side of the equation by 0.7 in order to get the x all by itself and find its value. 140 divided by 0.7 is 200. The number of students in the school is 200.

Factor The Trinomial<br><br> 6x^2 + 24x - 72<br><br> Show work/steps
Ymorist [56]

6x² + 24x - 72

Divide all the terms by the greatest common of factor of 6. Makes factoring easier. We will need to put this 6 on at the end so keep it in mind.

(6x² + 24x - 72) / 6 = x² + 4x - 12

Your simplified equation is x² + 4x - 12

Now to factor we must find out what two factors of - 12 can be added together to equal 4. The factors are 6 and -2:

x² - 2x + 6x - 12

Now we must group and factor.

(x² - 2x) + (6x - 12)

We can pull an x out of the first binomial because both terms have that in common:

x(x - 2) + (6x - 12)

We can pull a 6 out of the second binomial for the same reason:

x(x - 2) + 6(x - 2)

The terms inside the parentheses match each other, this means (x- 2) is one of the factors of the original trinomial. The other comes from the terms on the outside x and + 6. Put them together, (x + 6)

So your factors are (x - 2)(x + 6); this isn't it though. We need the 6 from the top, the one we divided out to make factoring easier. We will put it on the outside of whichever factor you list first so that your final answer reflects that to get back to the original trinomial, you would have to multiply the whole thing by 6.

Your final answer is:

6(x - 2)(x +6)
