Cosine(angle) = adjacent leg/ hypotenuse
Cosine( angle ) = 18/20
Angle = arccos(18/20)
Angle = 26 degrees
Answer:
2x(x − 3)(x + 3)
x(x + 4)(x + 2)
Step-by-step explanation:
2x³ − 18x
x(2x² − 18)
2x(x² − 9)
2x(x − 3)(x + 3)
x³ + 6x² + 8x
x(x² + 6x + 8)
x(x + 4)(x + 2)
Solution:
Given, x=-3, y=6, and z=4
Putting these values in the given equation:
-15+(-x)+y
= -15+(-(-3)+6
= -15+3+6
= -15+9
= -6
The quotient is : 5x-12+(25)/(x+3)
The remainder is : 25
you can conclude that lines A and B are parallel to each other
