Hello,
1) A odd function has the propriety f(-x)=-f(x)
Answer E
2)
if f(x) is even f(x)=f(-x)
if g(x) is even g(x)=g(-x)
h(x)=f(x)+g(x)=(f+g)(x)
h(-x)=(f+g)(-x)=f(-x)+g(-x)=f(x)+g(x)=(f+g)(x)=h(x)
h(x) is even
Since there is no image given, the perimeter is the sum of measurement of the sides of the triangle. Assuming that the triangle is equilateral. Then the perimeter of the triangle is equal to
P = x + x + x
P = 3x
P = 30 mm
The common denominator would be 6. Since, the least common multiple of 3 and 6 is 6.
3:
3, 6, 9
6:
6, 12, 18
Least common multiple is 6
Answer:
2.57 or 2.5703939893007399
