Complete the two-column proof.

given: < 2 = < 4, m< 2 = 110
proof: m< 3 = 70

< 2 = < 4, m< 2 = 110 given
m< 2 = m< 4 definition of congruent angles
m< 4 = 110
< 3 and < 4 are a linear pair definition of a linear pair(shown in diagram)
< 3 and < 4 are supplementary linear pair postulate
m< 3 + m< 4 = 180
m< 3 = 70

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,
