Answer:
x^4 - 81 = 0
(x² - 9)(x² + 9) = 0
Notice that the first of these is itself a difference of two squares:
(x - 3)(x + 3)(x² + 9) = 0
So the solutions are x = 3, x = -3, x = 3i, x = -3i
Answer:
107, there is two lines after that so 108 109 and the last line is 110 so your answer will be 107 degrees.
Step-by-step explanation:
Answer:
to solve this you need to find out what number n is to make it equal 28.
Step-by-step explanation:

hopefully this is right and this gets to you on time
Well round to the nearest cent means to the nearest .01
So if the number is ex .0328
You round to .03
And if the number is ex .06831
You round to .07
Meaning if the number after .01 or .0_ is greater than 5 than you round up and if it's 4 or lower than you keep the number there
Sorry can't do much if this is an actual problem because you only said round to the nearest cent.
