B Karen is working on her math homework. She solves the equation = 36 and says that the solution is
9
b = 4.
Do you agree or disagree with Karen?
Complete the explanation. If her answer is incorrect, find the correct answer.
You disagree y with Karen. The equation is a division equation that can be read as "b divided by 9 is
equal to
Karen solved it as if the equation were 9b = 36.
The correct ay to solve the problem is to ? both sides of the equation by 9.
So, b =

yes she correct

Step-by-step explanation: 36/9=4

step-by-step explanation:

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
