Answer: 5th degree trinomial
The degree is 5 because its the largest exponent of the single variable polynomial.
It's a trinomial because there are 3 terms. The terms are separated by a plus or a minus.
As given m is a midpoint of ab. So am is half of ab.
So we can write

As given am = 3x+3 , ab = 8x - 6.
So





So x = 6.
So length of am = 3x+3 = 3*6 + 3 = 21
Answer:
A
Step-by-step explanation:
The correct answer is A.
Try breaking the shape into other shapes that you can find the area for and then adding them together.
They have to pay the 30$ fee first then it depends on how many people are coming with you
Inverse variation means y=k/x, we are given (3,6) so
6=k/3
k=18 so
y=18/x
y=18/27
y=2/3
