You can tell how many zeros an equation has by if the equation is squared, cubed... In this equation, x^2 would have 2 zeros.
The right answer is <u>Many kids went directly from grammar school to special vocational schools sponsored by private agencies. . .</u>

Answer:
51 DVDs
Step-by-step explanation:
Let the number of DVDs and CDs sold be x each.
<u>Initial</u>
Number of DVDs= 86
Number of CDs= 52
<u>After selling</u>
Number of DVDs= 86 -x
Number of CDs= 52 -x
Given that there are 3 times as many DVDs than CDs left,
86 -x= 3(52 -x)
<em>Expand:</em>
86 -x= 156 -3x
<em>Bring x terms to 1 side, constant to the other:</em>
3x -x= 156 -86
<em>Simplify:</em>
2x= 70
<em>Divide both sides by 2:</em>
x= 35
Amount of DVDs left
= 86 -x
= 86 -35
= 51
Its a binomial
If zeros be alpha and beta
The answer is B, 1.625. If you need an explanation just ask!
