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.
P=26=2*(l+L)
⇒ l+L=26:2=13 feet
l=3, L=10
A=l*L=30=10*3
⇒ l=3 feet
L=10 feet
Answer:
x=10t+25
Step-by-step explanation:
The delivery fee is 25 dollars and each shirt is 10 dollars
Answer:
Option D will be correct.
Step-by-step explanation:
The 333 erasers cost $4.41.
We have to determine the cost of 444 erasers.
Let the price of 444 erasers is $x.
Therefore, since the number of erasers cost per dollars is constant, hence the equation that would help to determine the cost of 444 erasers will be 
⇒ 
Therefore, option D will be correct. (Answer)
