Cameron wants to measure a poster frame but he only has a sheet of paper that is 81/2 by 11 inches

Cameron wants to measure a poster frame, but he only has a sheet of paper that is 8 1/2 b 11 inches

he lays the long edge of the paper along the long edge of the frame several times and finds the frame is 4 papers long how long is this in inches

Step-by-step explanation:

Given.

The long edge of the paper is 11 Inches.

And Short edge or width of the paper is

According to question, he lays the long edge of the paper along the long edge of the frame several times and finds the frame is 4 papers long.

The long edge is 11 inches.

The long edge of the poster frame is four times of long edge of the paper that is  =

Hence the long edge of the poster frame is

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.
