use FOIL (first, outside, inside last)

4a * 3a = 12a²

4a * -8 = -32a

-6 * 3a = -18a

-6 * -8 = 48

-12a² - 32a - 18a + 48

combine like-terms: -12a² -50a + 48

Prove ABC~EDC ?

erastova [34]

Answer:

AA similarity theorem

Step-by-step explanation:

we know that

<u>AA (Angle-Angle) Similarity</u> states that In two triangles, if two pairs of corresponding angles are congruent, then the triangles are similar

In this problem we have that

∠BCA=∠ECD ----> by vertical angles

∠BAC=∠DEC ---> because AB is parallel to ED (alternate interior angles)

therefore

Triangles ABC and EDC are similar by AA similarity theorem
