The vertices of δabc are a (1, 5), b (3, 9), and c (5, 3). the vertices of δdef are d (−3, 3), e (−2, 5), and f (−1, 2). which conclusion is true about the triangles? a the ratio of their corresponding sides is 1: 3. b they are congruent by the definition of congruence in terms of rigid motions. c the ratio of their corresponding angles is 1: 3. d they are similar by the definition of similarity in terms of a dilation.

hello from mrbilldoesmath!

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

discussion:

in general, the factorization of a^3 + b^3 is

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

in our case note that 343 = 7^3 and 216 = 6^3 so the equation becomes:

343x^3 + 216y^3 = (7x)^3 + (6y)^3

if you think of a (above) as 7x and b as 6y the factorization becomes

343x^3 + 216y^3 =

((7x + 6y) (   (7x)^2 - 7x*6y + (6y)^2)   =

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