Can anyone help and show work

x=88⁰

Step-by-step explanation:

Since the value of that angle is 44⁰ and the angle is located on the circle, the measure of the arch x is twice the angle value.

So x=2×44⁰=88⁰

x = 80

Step-by-step explanation:

x = 44*2

x = 80

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)

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

no because mercury has a density of 13.6 grams per centimeter squared while gold has 19.32 grams centimeter squared
