Answer:

See proof

Step-by-step explanation:

       Statement                                             Reason

1. \triangle ABC, \overline{FC}\parallel \overline {BA} and \overline{FA} bisects \angle BAC - Given

2. \angle BAD\cong \angle CAD                                       - Definition of angle bisector

3. \angle BAD\cong \angle CFD                                       - Alternate interior angles theorem

4. \angle CFD \cong \angle CAD                                       - Substitution property

5. \bf{\angle ADB\cong \angle CDF}                                      - Vertical angles are congruent

6. \triangle ADB\sim \triangle FDC                                     - AA Similarity postulate

7. \dfrac{AB}{BD}=\dfrac{FC}{CD}                                                - Definition of similar triangles

8. AC=FC                                                  - Converse of base angles theorem

9. \dfrac{AB}{BD}=\dfrac{AC}{CD}                                                - Substitution property

What is (3x+5)(x^2+6x+11)
serg [7]

Answer:

\large\boxed{3x^3+23x^2+63x+55}

Step-by-step explanation:

\text{Use FOIL:}\\\\(a+b)(c+d)=ac+ad+bc+bd

(3x+5)(x^2+6x+11)\\\\=(3x)(x^2)+(3x)(6x)+(3x)(11)+(5)(x^2)+(5)(6x)+(5)(11)\\\\=3x^3+18x^2+33x+5x^2+30x+55\qquad\text{combine like terms}\\\\=3x^3+(18x^2+5x^3)+(33x+30x)+55\\\\=3x^3+23x^2+63x+55
