If DM = 25, what is the value of r? line segment DM with a point at g. segment dg = r+3 and segment gm = 4r -28

Group of answer choices

12

Step-by-step explanation:

The problem says that G is any point lying on line segment DM. So,

DG = GM

We have, DG = and GM = 4r-28

Putting values in above equation

r +3 = 4r-28

Taking like terms together

r-4r = -28-3

-3r = -31

So, the value of r 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.
