Astronomy New stars can form inside a doud of interstelar gas when a cloud fragment, or dump, has a mass M greater than
the jeans mass M, The Jean's mass is M,=100n (T+273)
where n is the number of gas molecules per cubic centimeter
and T' is the gas temperature in degrees Celsius. A gas dump has
M=137,11 1000, and T-263. Will the dump form a star

answer: sorry i dont really know but can we talk all my friends r gone and im bored

step-by-step explanation:

x^2 + 81

we can factor this using difference of square binomials.

rewrite the equation:

x^2 - (-81)

factor:

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

(x^2 - (-81) = (x + √-81)(x - √-81)

we can remove the - from under the radical by multiplying it by i.

(x^2 - (-81) = (x + i√81)(x - i√81)

(x^2 - (-81) = (x + 9i)(x - 9i)

we can check our answer by using foil:

x^2 - 9ix + 9ix - 81i^2

x^2 - 81^2

i^2 = -1

x^2 + 81
