Alva wants to prove that opposite sides in a parallelogram are congruent. A A B B C C D D E E Alva says: "I can prove this by establishing the congruence of a single pair of triangles." Which pair of triangles is Alva referring to, and which criterion should she use for establishing congruence? Choose 1 Choose 1 (Choice A) A △ A B C △ABCtriangle, A, B, C and △ C D A △CDAtriangle, C, D, A by angle-side-angle (Choice B) B △ A B C △ABCtriangle, A, B, C and △ C D A △CDAtriangle, C, D, A by side-angle-side (Choice C) C △ A B E △ABEtriangle, A, B, E and △ C D E △CDEtriangle, C, D, E by angle-side-angle (Choice D) D △ A B E △ABEtriangle, A, B, E and △ C D E △CDEtriangle, C, D, E by side-angle-side

i think c. but don't trust it.

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.

are ya tryin to ask something or is this a statement
