Answer:
Step-by-step explanation:
1) y = (cos x) / x is neither, since cos x is even and x is odd. Expressions such as this are neither even nor odd. /
2) y = (sin x) / x is even, since sin x and x would either both be positive at the same time or negative at the same time. Recall that (-) / (-) is positive, just as (+) / (+) is positive.
Neither ! X= -9/4 and Y=9
Opposite angels are congruent (D = B). Consecutive angles are supplementary (A + D = 180°)
72 = 2 * 2* 2 * 3 * 3
120 = 2 * 2 * 2 * 3 * 5
The greatest common factor (GCF) would be gotten from the factors common to both 72 and 120.
The common = 2 * 2 * 2 = 8
The GCF = 8
Answer: x(x+2)
Factor out x from the expression
X•(x+2)
