Given: ADFE is isosceles with base FE; FB EC.
Prove: ADFB - ADEC
D
We know that triangle DFE is isosceles with base FE
and that segment FB is congruent to segment EC
because
Segment DF is congruent to segment by the
definition of isosceles triangle. Since these segments
are congruent, the base angles, angles
are congruent by the isosceles
triangle theorem. Therefore, triangles
are congruent by SAS.

sorry, i'm new here and i'm just trying to figure this out. try quizlet. rate 5* you!

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

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.
