On the coordinate plane, plot and label these points: LaTeX: A = (2,1)A = ( 2 , 1 ), LaTeX: B = (5,1)B = ( 5 , 1 ), LaTeX: C = (7,2)C = ( 7 , 2 ), LaTeX: D = (4,2)D = ( 4 , 2 ) What is the length of LaTeX: CDC D? What kind of quadrilateral is LaTeX: ABCDA B C D?

the answer is c. hope this !

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.

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed

the correct answers i think are b. and d.

give me brainliest if it is correct!
