Omg I wish I could help I am not in this top level ♂️
1. The first polynomial listed is just the number 9.
We can identify two key things here:
There is one term, so it's a monomial.
There are no factor's, so it has a degree of 0, or is constant.
Your answer is correct.
2. In the next polynomial, we can identify the same things:
There are three terms, so it's a trinomial.
The degree of the polynomial is determined by observing the higher power in a given term, in this case, it's three.
The prefix for relating to a multiple of three is cubic, we so know that this is a cubic trinomial.
Your answer is correct again, well done!

Answer:
central angle=18
arc length=2.5 π feet
area of a sector=31.25π square feet
Step-by-step explanation:
Given
wheel radius=25 feet
attached cars=20
Space between cars along the circumference of wheel= 360/20
=18
Finding arc length:
arc length= radius x angle(in radians)
angle in radian = 18 x π/180 = 0.1π radians
arc length = 25 x 0.1π
=2.5π feet
Area of the circle = πr^2
Area of the circle = π(25)^2
Area of the circle = 625π square feet.
As the ratio of the central angle to the full circle angle is proportional to the area of the sector to the complete circle:
central angle/360=area of sector/area of circle
Area of sector= area of circle x 18/360
= 625π(1/20)
=31.25π !
7 < 2x = 25
6x + 12 > 32 (put a line under the greater than sign)
x/5 = 22
18 < 3/4b = 23
