Although you didn't provide any answer choices:
A trinomial is an expression with exactly three terms that can't be combined an example would be this
x^2 - 3x + 1
None of those terms can be combined
x^2 + 3 - 4 has three terms but it isn't considered a trinomial because you can simplify it to x^2 - 1 which is known as a binomial because it has 2 terms in it's simplified form.
hope this helps C:

Answer: XWY and STR</h3>
I tend to think of parallel lines as train tracks (the metal rail part anyway). Inside the train tracks is the interior region, while outside the train tracks is the exterior region. Alternate exterior angles are found here. Specifically they are angles that are on opposite or alternate sides of the transversal cut.
Both pairs of alternate exterior angles are shown in the diagram below. They are color coded to help show how they pair up and which are congruent.
A thing to notice: choices B, C, and D all have point W as the vertex of the angles. This means that the angles somehow touch or are adjacent in some way due to this shared vertex point. However, alternate exterior angles never touch because parallel lines never do so either. We can rule out choices B,C,D from this reasoning alone. We cannot have both alternate exterior angles on the same exterior side of the train tracks. Both sides must be accounted for.
Answer:
All the left numbers of the Ratio go by 8's times tables and all the right numbers go by 5's times tables
Step-by-step explanation:
8x1= 8
8x2 =16
8x3 = 24
5x1= 5
5x2= 10
5x3= 15
Let me know if its right.
