multiply and simplify.
(x - 3)(x^2 + 3x + 9)

a)
x^3 - 27

b)
x^3 - 27x^2

c)
x^3 - 6x^2 + 3x - 27

d)
x^3 - 9x^2 + 6x - 27

A) x^3-27

Step-by-step explanation:

start by multplying x to the numbers in the second set of parenthesis:

x^3+3x^2+9x

then multiply the -3 to the numbers in the second set of parenthesis:

-3x^2-9x-27

add these together:

(x^3+3x^2+9x) + (-3x^2-9x-27)

the 3x^2 and -3x^2 cancel as do the 9x and -9x so you are left with x^3-27

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
