21x - 19 = 3x + 17 |add 19 to both sides
21x = 3x + 36 |substract 3x from both sides
18x = 36 |divide both sides by 18
x = 2
Answer:
51 deg
Step-by-step explanation:
Sin W=0.7771
(use calculator)
W = 50.996 deg
= 51 deg (to nearest degree)

Answer: Choice C) x^4 - 2</h3>
Explanation:
If the exponent is negative, then that means we apply the reciprocal. So something like x^(-2) becomes 1/(x^2). A polynomial cannot have a variable in the denominator like this. So we can rule out choices A, B, and D. Choice C is the only thing left. It is a polynomial because the exponent is a positive whole number.
