5x5x5=125 so it could be x=5
Well, This Is Saying:
17•13•7x
So One Equation That Would Be Equivalent is
221*x
Another Would Be
1547x
First find the percentage of students who didn't like reading mystery stories.(100-85=15)
If 15% =30students
85%=?
85/15*30=170
Therefore 170 students liked reading mystery stories
Answer: " y = 21 " .
____________________________________________
Cross multiply:
______________________________
(2y)(4) = 7(y + 3) ;
8y = 7y + 21
Subtract 7y from each side of the equation;
8y - 7y = 7y + 21 - 7y ;
y = 21 .

Answer:
The graph is not shown, so I will answer the question in general terms.
The factor of the polynomial has the form x - x1, where x1 is a root of the polynomial. This means that at x1, f(x) = 0. Then, to answer your particular question, you need to see at which value of x, the function intercepts the x-axis, and that is your x1.
