A student believes she can prove the two triangles below are congruent using the SSS postulate. Complete the list of congruent corresponding parts so that she has enough information to prove the triangles are congruent.

it's C. BD is equal to DB .

Step-by-step explanation:

the last pair of side, which can be proved equal are BD and DB because the sides are common in both the triangles, making the triangles congruent by SSS Postulate...

hope this is what you were asking for!

step-by-step explanation:

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,
