Answer:
<h3>a. Give an example for which Arial's claim is true.</h3>
If linear relations have equal coefficient about the independent variable, then those linear relations are parallel. For example,
and
.
Notice that the coefficient of the dependent variable must be also equal, otherwise it would change the slope of the expression and they wouldn't be parallel.
<h3>b. Give an example for which Arial's claim is false.
</h3>
The statement is not false.
<h3>c. Suggest an improvement to Arial's claim.</h3>
An improvemente would be that the constant term no need to be equal too, between linear relations, because they can be at "differecent heights", sort of speak.

Answer:
2nd level = 5000
3rd level = 7500
4th level = 10000
Step-by-step explanation:
multiply 2500 x the level
12 *16 = 192
1/2 *20*10 = 100
192 +100 = 292 square units
