Answer:
option 4
Step-by-step explanation:
(f*g)(x) =(x² + x+ 1)*(x² - x -1)
= x²*(x² - x -1) + x(x² - x -1) + 1*( x² - x -1)
= x²*x² - x²*x -x²*1 + x*x² - x*x -x*1 + x² - x -1
= x⁴ - x³ - x² +x³ - x² - x + x² - x -1
= x⁴ - x³ + x³ - x² - x² + x² - x - x - 1
= x⁴ - x² - 2x - 1
Answer: C, WXZ and WXU are adjacent angles.
Step-by-step explanation:
A is incorrect because TUX and VUS are vertical angles.
B is incorrect because YXZ and TUX have no relationship.
C is correct because WXZ and WXU are supplementary angles, thus adjacent.
D is inccorect because VUX and TUS are vertical angles.
Use the pythagorean theorem. It would be set up as
a^2 + 3.7^2 = 4.0^2
Answer:
s = 180
