To check whether a function is odd or even, we simply substitute the argument by its negative version, namely "x" by "-x".
if the expression simplifies to resemble the original expression, that simply means the expression is
even. If it resembles the original negative expression, is
odd.
well, that doesn't look like the original
- 2x³ - 9, so is not
even.
and -f(x) would be
2x³ + 9, and that doesn't look like either, so is not
odd.
thus is neither.
The triangles are similar by the AA similarity theorem, therefore, the answer is: (b) yes, because ∠QUR ≅ ∠TUS (vertical angles) and ∠r ≅ ∠s (alternate interior angles).
<h3>What is the AA Similarity Theorem?</h3>
If two angles in one triangle are said to be the same or congruent to two corresponding angles in another triangle, based on the AA similarity theorem, the two triangles can be proven to be similar triangles.
In the diagram given, we know that: angles QUR is congruent to angle TUS based on the vertical angles theorem.
We also known that, alternate interior angles, angles R and S are congruent.
This means that both triangles have two pairs of corresponding congruent angles. We can prove that they are similar to each other by the AA similarity theorem, therefore, the answer is: (b) yes, because ∠qur ≅ ∠tus (vertical angles) and ∠r ≅ ∠s (alternate interior angles).

Speed = distance / time => time = distance / speed
speed = 3x10^8 x 60 = 180x10^8 m per minute
time = 1.5x10^11/180x10^8 = 150x10^9/180x10^8 = 5/6x10 = 8,3 minutes
Answer: factorizar x de x ^ 2 + 5x.
x (x + 5)
Step-by-step explanation:
Answer:
1.375
Step-by-step explanation:
3/4 is 0.75,
5/8 is 0.625
so 0.75 + 0.625=1.375
