Answer:
-9x
Step-by-step explanation:
Without the confusing parentheses, this "polynomial" becomes -8x + x -2x. If we take 2 away from -8, it becomes -10. If we add a positive x, it becomes -9x. Therefore, the answer is (the monomial) -9x.
Answer:
235,305
Step-by-step explanation:
sin theta = -.8190
Take the arcsin of each side
arcsin sin theta = arcsin -.8190
theta = -54.9825
But that is not between 0 and 360
so add 360
360+-54.9825 = 305.0175
It is also in the third quadrant because of the negative sin
theta = 180+ 54.9825 = 234.9825
To the nearest degree 305 and 235
x is just a stand-in for an unknown/variable number, so we could use phrases like "a number," "a value," "an unknown," etc. Here, I'll use "a number." We can verbally refer to the result of subtraction as "the difference" as well, so we can write x - 6 in English as "The difference of a number and 6."
