I think it is 3 djdodnekosowje
The correct answers among the choices presented above are options B and D. Two ways to verify that solutions are correct are done by graphing the equations and see where they meet and by s<span>ubstitute back into both equations. The intersection of the graph signifies the solution. Also, when after substituting the solutions to both equations and they satisfy the equality then it is correct.</span>
Answer:

Step-by-step explanation:

The other parallel side is 44 m
Step-by-step explanation:
Let us revise the formula of the area of a trapezium
, where
and
are its parallel bases- h is its height (The distance between the two parallel bases)
∵ The area of a trapezium is shaped field is 480 m²
∴ A = 480 m²
∵ The distance between two parallel sides is 15 m
∴ h = 15 m
∵ One of the parallel side is 20 m
∴
= 20 m
We need to find 
Substitute all these value in the rule of the area below
∵ 
∴ 
- Multiply the two sides by 2
∴ 
- Divide both sides by 15
∴ 
- Subtract 20 from both sides
∴ 
The other parallel side is 44 m

Okay to find the unit rate you must find how much one bucket of paint costs so you divide 70.50/5 and then you will get 14.1 have a nice day (:
