Answer:
D
Step-by-step explanation:
Remember that the sum of the interior angles of a triangle will always total 180.
Therefore:
Let’s solve for <em>x: </em>
Combine LIke Terms:
Add:
Subtract 80 from both sides:
Divide both sides by 25:
Therefore, the value of <em>x </em>is 4.
Now, to find A, we can substitute it for A.
A is measured by:
Substitute 4 for <em>x</em> and evaluate:
Hence, our answer is D.
The function
f(x) is even
g(x) is neither even nor odd
h(x) is odd
Steps:
for an even function it holds that f(-x) = f(x):
f(-x) = (-1)^6 x^6 - (-1)^4 x^ 4 = x^6 - x^4 = f(x) => f is even
for an odd h(x) it holds that h(-x) = -h(x):
It is easy to show that g(x) does not match any of the two possibilities above.
