Answer:
x = 3
Step-by-step explanation:
The equation can be rewritten to make use of the graphing calculator's ability to identify function zeros:
x(x -2)(x +3) -18 = 0
The attached shows x = 3 is the only real solution.
_____
We're not sure what "system of equations" is intended. Perhaps it is ...
y = 18
y = x(x -2)(x +3)
To create the expression we graphed, we effectively subtracted the first equation from the second.

Answer:
20+6n
Step-by-step explanation:
Tara's point total is found by adding up the points in each game ...
20 + n + n + n + n + n + n
= 20 +6n
_____
Of course, we use multiplication to simplify repeated addition.
