Step-by-step explanation:
<span>take 5x as a factor of each term
5x(x^2 -4x - 12)
you now need to factor the quadratic...

X = 24
How?
First, plug in “27” to y.
3x - 2(27) = 18
Next, multiply the numbers
3x - 54 = 18
Now, add 54 to both sides.
3x = 18 + 54
Combine the like terms.
3x = 72
Finally, divide both sides by 3.
X = 24
Answer:
6.47 gal
Step-by-step explanation:
cost of gas per gallon = $2.78
rate of change is cost of gas per gallon as cost to buy gas changes with the change in quantity of gallon.
Total cost for x gallons = cost of gas per gallon*x = 2.78x
Given that total money paid by him is $18
2.78x = 18
x = 18/2.78 = 6.47
