Step-by-step explanation:

solution:

given:- BE is bisector of ∠DBC and BE//AC

          statement                                                  reasons

   1. ∠DBE= ∠BEC                                  1. since, BE is bisector of ∠DBC

   2.∠DBE=∠BAC                                  2. corresponding angle are equal

                                                                   are equal.

 3.∠EBC=∠BCA                                    3. alternative angle are equal

 4.∠BAC=∠BCA                                    4. from statement 1,2,3

5 therefore, triangle ABC is                 5. if base angle are equal it is a an    isosceles triangle                                      isosceles triangle                                                                                                              

 6. AB=BC                                              6.corresponding sides of equal angle                    

                                                                isosceles triangle are equal

 proved

range is infinite on both x and y axis positive and negative

step-by-step explanation:

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
