Given m|n, find the value of x.
kt
xº
779

x = 103ᴼ

Step-by-step explanation:

These angles are supplementary, meaning they add to equal 180ᴼ. So, to find the missing angle (or x in this equation), you subtract 77 from 180.

180 - 77 = 103

x = 103

Step-by-step explanation:

x and 77 are same- side exterior angles and are supplementary, thus

x = 180° - 77° = 103

35 is an outlier

step-by-step explanation:

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)

you,

mrb

(a + b) (a^2 - a b + b^2)
